The floor system is one of the most weight consuming systems in a building, around 20%. If we take into account the costs of the slab system separately:formwork consumes 45% - 55% of the slab cost, therefore a regular slab and without changes in the layout and shape in every floor will give us a better result; 30% - 35% of the cost is given by How to Calculate CWT BizfluentNov 21, 2018 · If this volume-based weight is greater than the actual weight, you must use it to calculate the freight charges. For example, if the shipper's formula produces a volume-based figure of 1,800 pounds and the actual weight is 1,680 pounds, use 1,800 pounds. Once you know the billable weight, convert to CWT by dividing by 100.

This paper proposes a novel integrated design strategy to accomplish simultaneous topology shape and sizing optimisation of a two-dimensional (2D) truss. An optimisation problem is posed to find a structural topology, shape, and element sizes of the truss such that two objective functions, mass and compliance, are minimised. Design constraints include stress, buckling, and compliance. Solved:A gravity retaining wall is shown in Figure 1 A gravity retaining wall is shown in Figure 1.
