Concept explainers

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).

Estimate the loads applied on the Beam 1, including the load transferred from Slabs 1 and 2 (self-weight of slabs), the self-weight of Beam 1 and the water tank load. Note that the water tank load may be idealised as a point load. Please also note that there are also other types of loads, which should be considered for practical design, but for simplicity they are not considered here.
