A.ETABS :FULL FORM: Extended 3D Analysis of Building Systems

NumericalMethod: The characteristic properties of a buildings mathematical

model, thereby allowing the graphical creation of a buildings model in the samesequence that it will actually be constructed

Primarily used for: This program is optimized for modeling building systems

Limitations of that software: it works only node to node

Software developed by: Computers and Structures, Inc.

B.SAP 2000FULL FORM: Structural Analysis Program

Numerical Method: Solvers that have been tried and tested by the industry for over

35 years.

Primarily used for: general-purpose civil-engineering software ideal for the analysis

and design of any type of structural system.

Software developed by: Computers and Structures, Inc.

C. STAAD PROFULL FORM: Structural Analysis and design

Numerical Method: Finite element analysis

Primarily used for: allows structural engineers to analyze and design virtually any

type of structure through its flexible modeling environment, advanced features and

fluent data collaboration.

Limitations of that software: While analyzing frames with uniformly varying load

if a node is inserted in the beam there is error in the fixed end moment.

IMPROVEMENTS OF SAP 2000 v14 OVER SAP2000 v11

A Quick-Start option is provided for easy modeling of reinforced concrete

sections. Nonlinear Shear wall capabilities

Material-based damping is available for linear and nonlinear direct-integration

time-history analysis. Material-based damping is available for steady-state and PSD analysis.

A nonlinear, layered shell element using a directional material model has been

added for pushover analysis of shear-wall structures and similar applications.

Stiffness-proportional damping uses initial stiffness instead of tangent stiffness to

improve the consistency of results and convergence behavior.

Section Designer has been enhanced for the display of fiber-model PMM surface.

The default material properties for concrete have been modified to improve

convergence behavior.

The tangent stiffness used for the iteration of fiber hinges and multi-linear linkshas been changed to improve convergence.

Material-based damping is available for steady-state and PSD analysis.

The rigid-response calculation in response-spectrum analysis has been enhanced

for NRC and general use.

Base reactions for response-spectrum and modal time-history analysis have been

improved for springs and grounded link supports to better capture missing-mass

effects.

Base reactions no longer include constraint forces at restraints, for consistency.

Fully automated bridge design check per AASHTO Guide Specifications for

LRFD Seismic Bridge Design 2009 has been implemented, including pushover

analysis when required.
