Connections

In steel structures, connections are the members that join two or more steel members. The connections are the most important members of any steel structure, and hence, they are designed more carefully. The majority of the construction cost of steel structures is incurred due to the connections. The design of connections is done as per the recommendations and specifications of the American Institute of Steel Construction (AISC).

Question

For the lateral bracing truss shown in Fig. 3, check the compressive capacity of the
member for the following two cases: (a) the member is a single angle member (200
x 150 x 18, grade S275) connected to long leg and (b) the member is a single channel
member (305 x 89, grade S355).
