Task to be carried out.

We were provided with two truss models: one is determinate, and the other one is indeterminate. We are tasked with analyzing both trusses and designing the more economical option among the two..

Applied Methodology.

Step 1: We have various load combinations, out of which one is selected that results in the maximum load. Calculations shown below.

We applied this critical load combinations to the determinate truss and analyzed using SAP2000. Below are the results.

Determinate Truss VS Total weight of determinate truss = 484kg or 1069.2lbs Weight Price per kg = 244rs Total price according to member weight = 236,672rs (excluding lateral connection) Price The determinate truss has a top chord in compression while bottom chord in tension which shows that determinate truss can expand in case of loading. Behavior Indeterminate Truss Total weight of indeterminate truss = 516kg or 1138.8lbs Weight Price per kg = 244rs Total price according to member weight = 252,084rs (excluding lateral connection) Price The indeterminate truss has all members in compression. It cannot move horizontally or vertically. All the members are kind of confined between both hinges and hinges provide equal and opposite reactions. Behavior Determinate vs Indeterminate Truss.
