FOURTH SCHEDULE

Regulations27 (a),44, 79, 82 and 83LOADING

1. SCOPE

1.1 This Schedule gives the dead and minimum recommendedimposed loads for use in designing buildings and other works for whichplans are submitted to the Commissioner of Building Control under the Actand these Regulations. It applies to-

(a) new buildings and building works;(b) alterations and additions to existing buildings; and(c) existing buildings where change of use is involved.

1.2 This Schedule does not apply to the maintenance of or thereplacement of parts of existing buildings where change of use is notinvolved.

1.3 The SI unit of force and load is the Newton; it is that force which,when acting on a mass of 1 kg, imparts to it an acceleration of 1 m/s 2.

1.4 This Schedule does not cover -(a) loads on road and rail bridges;(b) loads due to vibration, except those due to some gantry

cranes;(c) loads due to lifts;(d) loads incidental to construction;(e) test loads;(I') accidental loads; and(g) loads on structures subject to internal pressure from their

contents (e.g. bunkers, silos and water tanks).

2. DEAD LOADS

2.1 Dead loads shall be calculated from the unit weights given in BS648 or from the actual known weights of the materials used.

2.2 Where permanent partitions are shown in the plans, their actualweights shall be included in the dead load.

2.3 The weights of tanks and other receptacles, and of their contents,shall be considered as dead loads. These loads shall be calculated for thecases when a tank or receptacle is full and when it is empty.

3. IMPOSED FLOOR AND CEILINGLOADS3.1 General

3.1.1 The loads appropriate to the different uses to which theparts of a building or structure may be put are given inTables 5 to 12. A key to the groups in these tables is givenin Table 1. The distributed loads are the uniformlydistributed static loads per square metre of plan area andprovide for the effects of normal use. Where, in Tables 5 to12, no values are given for concentrated load, it may beassumed that the tabulated distributed load is adequate fordesign purposes.

3.1.2 All floors shall be designed to carry the appropriatedistributed or concentrated imposed loads given in Tables5 to 12. Where recommendations are not given, theappropriate load will be whichever produces the greaterstresses in the part of the floor under consideration. In thedesign of floors, concentrated loads are considered to beapplied in the positions which produce the maximumstresses and, where deflection is the design criterion, in thepositions which produce maximum deflections. Theconcentrated load may not be considered where the floorsare capable of effective lateral distribution of this load.

3.1.3 Concentrated loads when used for the calculation ofbending and shear are assumed to act at a point. Whenused for the calculation of local effects, such as crushing orpunching, they are assumed to act over the actual area ofapplication.

3.1.4 The imposed loads for beams are the distributed loadsappropriate to the uses to which they are to be put, asgiven in Tables 5 to 12.

3.1.5 The general recommendations are not applicable tocertain unusual uses particularly where mechanicalstacking, plant or machinery are to be installed and inthese cases the designer should determine the loads from aknowledge of the equipment and processes likely to beemployed.

3.1.6 When partitions are indicated on the plans, their weightshould be included in the dead load acting asconcentrated loads in their actual positions. When thepartitions are not determined on the plans, and additionalimposed load on beams and floors {where these arecapable of effective lateral distribution of the load} may betaken as a uniformly distributed load per square metre ofnot less than one-third of the weight per metre run of thefinished partitions. For floors of offices the uniformlydistributed load shall not be less than 1.0 kN/m2.

- 211-



3.2 Ceiling Supports and Similar Structures

3.2.1 The following loads shall be adopted in the design offrames and coverings of access hatches (other thanglazing), the supports of ceilings and similar structures:(a) without access - no imposed load; or(b) with access - 0.25 kN/m 2 uniformly distributed over

the whole area or the area supported and aconcentrated load of 0.9 kN so placed as to producemaximum stresses in the affected members.

4. REDUCTION IN TOTALIMPOSED FLOOR LOADS

4.1 No reduction shall be made for any plant or machinery which isspecifically allowed for, or in buildings designed for, storage purposes.

4.2 Except as provided in 4.1 and 4.3, the reductions given in Table 2and Table 3 may be applied to the total imposed floor load (including theadditional partition loading allowance given in 2.2) in designing columns,piers, walls, beams and their supports and foundations. Where the floorload given in Tables 5 to 12 exceeds 5 kN/m 2 the reductions given inTable 2 may be taken provided that the loading assumed is not less than itwould have been if all floors had been designed for 5 kN/m2 with noreductions. The reductions given in Table 3 do not apply to roofs.

5. IMPOSED ROOF LOADS

5.1 General

5.1.1 In 5.2 to 5.5 inclusive, all roof slopes are measured fromthe horizontaland all loads are applied vertically.

5.2 FlatRoofs

5.2.1 The imposed load on flat roofsand slopingroofs up to andincluding 10., where access (in addition to that necessaryfor cleaning and repair) is provided to the roof, is 1.5 kN/m2 measured on plan or a 1.8 kN concentrated load,whichever produces the greater stress.Where deflectionisthe design criterion, the concentrated load is assumed toact in the position which produces maximum deflection.

5.2.2 The imposed load on flat roofsand slopingroofs up to andincluding 10., where no access is provided to the roof(otherthan that necessary for cleaning and repair), is0.75kN/m2 measured on plan or a 0.9 kN concentrated load,whichever produces the greater stress.Where deflectionisthe design criterion, the concentrated load is assumed toact in the position which produces maximumdeflection.

5.3 Sloping Roofs5.3.1 The imposed loads on roofs with a slope greater than 10',

where no access is provided to the roof (other than thatnecessaryfor cleaning and repair),are as follows:

(a) For a roof-slope of 30. or less: 0.75 kN/m2 measuredon plan or a 0.9 kN concentrated load, whicheverproduces the greater stress. Where deflection is thedesign criterion, the concentrated load is assumed toact in the position which produces maximumdeflection.

(b) For a roof-slope of 75. or more: zero load.

5.3.2 For roof slopes between 30. and 75., the imposed loadmay be obtained by linear interpolation between 0.75 kN/m2 for a 30. roof slope and zero for a 75. roof slope.

5.4 Curved Roofs

5.4.1 The imposed load on a curved roof is calculated bydividing the roof into not less than 5 equal segments andthen by calculating the load on each, appropriate to itsmean slope, in accordance with 5.2 and 5.3.

5.5 Roof Coverings5.5.1 A loading of 0.9 kN on any square with a 125 mm side

provides for loads incidental to maintenance on all self-supporting roof coverings at a slope of less than 45., Le.,those not requiring structural support over their wholearea. No loads incidental to maintenance are appropriateto glazing.

6. CRANE GANTRY GIRDERS

6.1 This clause applies only to single-crane operation and to simpleforms of crane gantry construction. Loads for heavy cranes, high-speedoperation or multiple cranes on a single-gantry have to be speciallycalculated.

6.2 For crane gantry girders, the following allowances can be used tocover all forces set up by vibration, shock from slipping of slings, kineticaction of acceleration and retardation and impact of wheel loads:

(a) for loads acting vertically, the maximum static wheel loadsincreased by 25% for an electric overhead crane or 10%for a hand-operated crane;

(b) for the horizontal force acting transverse to the rails, thefollowing percentage of the combined weight of the craband the load lifted:

(i) 10% for an electric overhead crane; or(ij) 5% for a hand-operated crane; and

(c) for the horizontal forces acting along the rails, 5% of thestatic wheel loads which can occur on the rails, foroverhead cranes which are either electric or hand-

operated.

- 215-



6.3 The forces specified in either (b) or (c) above may be considered asacting at the rail level and being appropriately transmitted to the supportingsystems.

6.4 Either of the horizontal forces in (b) or (c) above may act at thesame time as the vertical load on gantry girders and their vertical supports.

7. DYNAMICLOADING (EXCLUDINGWIND)

7.1 The values for imposed load given in Tables 5 to 12 allow for smalldynamic effects, such as those due to the usual movement of people anditems of furniture. The loads do not necessarily allow for the dynamic effectof machinery (e.g. rotating and/or vibrating machines, braking andacceleration of forklifttrucks) nor do they allow for dynamic loads due tocrowds.

7.2 Inthe latter cases, the magnitude of the load effect depends on theresponse of the structural system (e.g. the floor) and can be considerablyhigher than the static load effect. The response of the system depends onseveral inter-related parameters, such as its mass, damping, naturalfrequency and mode shape, and therefore the use of a factored imposedstatic load to represent significantdynamic effectsmay prove inadequate.

8. VEHICULARBRIDGELIVELOADS

8.1 Live loads for vehicular bridge design shall comply with BS 5400except that -

(a) for HA Uniformly Distributed Load (UDL) a factor of 1.4 shallbe applied to the uniformly distributed load specified inBS 5400;

(b) for HA Wheel Load a separate load case of an axle consistingof 2 numbers of 120 kN wheel loads spaced at 2,000 mmapart transversely shall be considered. This is in addition tothe 100 kN HA wheel load case specified in BS5400;

(c) for HB Load the structure shall be designed for 45 units oftype HB loading. One HB vehicle shall be considered onthe bridge with no other traffic load concurrently presentand the HB vehicle may be considered to be confinedwithin a 5,000 mm strip along the centre of thecarriageway;

(d) for Longitudinal Braking and Traction Load for HA Load, thenominal longitudinal load resulting from traction orbraking of vehicles under HA loading shall be 10 kN/m ofloaded length plus 200 kN subject to a maximum of 800kN applied to an area one notional lane wide multipliedby the loaded length.

- 216-



9. WIND LOAD

9.1 Wind load shall be taken into account when designing buildings,structures and components thereof.

9.2 The manner of calculating such wind loads, including the adoptingof suitable wind pressures at varying heights or for different structuralshapes and other factors that may be involved, shall be in accordance withthe provisions of BSCP 3, Chapter V; Part 2.

10. PARAPETSAND BALUSTRADES

10.1 The loads appropriate to the design of parapets and balustrades aregiven in Table 4. Parapets and balustrades should be designed to resist theloads given in Table 4 when separately applied. The loads are expressed asminimum horizontal forces acting at a height of 1.1 m above datum level,irrespective of the actual height of the barrier. For this purpose the datumlevel should be taken as the finalised level of the access platform, or thepitch line drawn through the nosings of the stair treads.

10.2 In Table4 -(a) fixed seating is seating where its removal and the use of the

space for other purposes is improbable;(b) the dimension of 530 mm is taken to be the minimum

distance measured from any part of the fixed seating to thebarrier; and

(c) tip-up seats shall be considered in the up position.

11. VEHICLEBARRIERSFOR CAR PARKS

11.1 The horizontal force F (in kN), normal to and uniformly distributedover any length of 1.5 m of a barrier for a car park, required to withstandthe impact of a vehicle is given by:

F = 0.5mv2oc + ob

where-

m is the gross mass of the vehicle (in kg);v is the velocity of the vehicle (in m/s) normal to the barrier;oc is the deformation of the vehicle (in mm);ob is the eflexion of the barrier (in mm).

11.2

(a) Where the car park has been designed on the basis that themass of the vehicles using it will not exceed 2,500 kg, thefollowing values are used to determine the force F:

m = 1,500 kg (Themass of 1,500 kg is taken as morerepresentative of the vehicle populationthan the extreme value of 2,500 kg);

v = 4.5 m/s;oc = 100 mm unless better evidence is available.

(b) For a rigid barrier, for which _b may be taken as zero, theforce F appropriate to vehicles up to 2,500 kg gross mass istaken as 150 kN.

11.3 Where the car park has been designed for vehicles whose grossmass exceeds 2,500 kg the following values are used to determine theforce F.

m is the actual mass of the vehicle for which the carpark is designed (in kg);

v = 4.5 m/s;oc = 100 mm unless better evidence is available.

11.4 The force determined as in 11.2 or 11.3 may be considered to act atbumper height. In the case of car parks intended for motor cars whose grossmass does not exceed 2,500 kg, this height may be taken as 375 mm abovethe floor level.

11.5 Barriers to access ramps of car parks have to withstand one half ofthe force determined in 11.2 or 11.3 acting at a height of 610 mm above theramp.

- 219-



11.6 Opposite the ends of straight ramps intended for downward travelwhich exceed 20 m in length the barrier has to withstand twice the forcedetermined in 11.2 and 11.3 acting at a height of 610 mm above the ramp.
