ELEVATION ALONG GRID A

PART I. PROBLEM Description

You are asked to design a simple temporary scaffolding system for a construction site shown below. The structure is composed of $4$ levels of platform, Each level is made of $25mm$ thick steel plate that will be supported by a W$18$X$35$ Steel beam.

The steel beams wil be SIMPLY SUPPORTED by a Steel columns. The Steel plate will rest on top of the steel beam and will NOT be welded, NOR BOLTED on the top flanges of the beam. Instead, a C$-$Channel will be located between the beams as shown in the plan and will provide LATERAL SUPPORT for the Steel Beam. Also, the steel plate wil act like a ONE$-$WAY SLAB $($will transfer only its load along the shorter dimension of the plate$)$

The steel columns are $12m$ high, with lateral bracing supports at every $3m.$ The bottom of the Steel column is fixed while the top is pinned but will move horizontally $($with translation$).$

The following are the load and design parameters to be used.
