Lateral System

AdvantagesEliminate high cost of steel moment connectionsReduce steel erection time by eliminating steel moment connections

Six reinforced concrete shear wallsFour located on the perimeter

Extend all five floorsTwo located in the interior

Only extend four floorsVery rigid, very small deflections

Massive walls and footings to resist overturning moments



Lateral System

Questions


Kania SOM / Brennan HallWireless LAN Breadth Study

Wireless LAN

AdvantagesLess wire and cable throughout buildingMore flexible systemReduce overhead costs caused by moves, extensions to networks, adding individualsCan serve as hotspot for students with laptopsCan connect other buildings to same network

Installing network in older buildings is easy

802.11a64 users per access pointLower possibility of interferenceGood for; dormitories, computer labs, conference rooms, VoIP



Access Points

64 users per access pointConnected via ethernet to wired backbone

Diagram showing approximate locations of wireless access points



IP Phones

PC Based PhonesSoftware that allows all computers to be used as internet protocol phonesEach individual’s extension follows them to any computer he/she is logged on toProvides every feature that standard phones offerTeleconferencing capabilities

Desktop IP PhonesConnected via ethernet to wired backboneLocated in secretary/waiting areas



Interactive Whiteboards

Replaces chalkboard, overhead projector and screenCan function simply as a whiteboardCan display computer imagesCan save handwritten notes to print or post on course websites

Video Conferencing

Built in conferencing with multiple video and audio sitesDual LCD monitorsAdd a PC to the meetingSee live PC presentations and presenter simultaneously
