Shear forces and axial loads obtained from the portal method and spacegass

Due date: 7th September 2020
Individual project
Weighting: 15%

A multi story building is to be designed and constructed in Melbourne’s eastern suburbs. A preliminary assessment by the engineer has nominated that a concrete framed building would be most suitable. The engineer has nominated the geometry of the structure as per figures 1 and 2 below.

As the cadet engineer on the project, you are requried to perform the following tasks:

1. Based on AS1170.0, the designer has determined that two load combinations for ultimate limit state

2. Using the portal method, determine the factored bending moments, shear forces and axial loads for the frame. The bending moments, shear forces and axial loads should be determined independently using both load combinations for [Ed1 & Ed2] specified in part 1. Note that to determine the moments and forces using load combination Ed1, the moments, shear forces and axial loads due to wind loads and gravity loads will need to be determined separately and combined using the principal of superposition.
