Introduction

• The bridge is located in Mawson Lakes between the
  two G buildings
• Connects the two buildings
• Used by people to travel and transport goods from
  one building to the other.

Objectives

• To analysis the static behaviour of the bridge
• - determining the stress,deflection acting on the
  bridge under different loading conditions.
• Determine the points of maxima
• Develop an understanding of Stran7

Member specification

• Beams 30X30cm
• -Floor beams3.2m high
• -Top beams2.4m
• Floor (slab) thickness30cm
• Roof thickness25cm

8
Loading conditions

• Three loading conditions to be examined
• Dead Load, G, due to self-weight
• Live load, Q
• Wind Load

Conclusion

• The bridge had small displacement under all
  loading condition considered
• There were some difficulties in modeling some
  other part of the bridge e.g stairs
• Maximum displacement and stress mostly in the
  middle of the bridge as expected
