The loads can be self weight of the structures,
other dead load, live loads, moving (wheel) load, wind load, earthquake load,
load from temperature change etc. The structural engineer must design
structures to be safe for their users and to successfully fulfill the function
they are designed for (to be serviceable). Due to the nature of some
loading conditions, sub-disciplines within structural engineering have emerged,
including wind engineering and earthquake engineering.[23]
Design considerations will include
strength, stiffness, and stability of the structure when subjected to loads
which may be static, such as furniture or self-weight, or dynamic, such as
wind, seismic, crowd or vehicle loads, or transitory, such as temporary
construction loads or impact. Other considerations include cost,
constructability, safety, aesthetics and sustainability.
Structural engineering is concerned with the structural design and structural analysis of buildings, bridges, towers, flyovers, tunnels, off shore structures like oil and gas fields in the sea, and other structures. This involves identifying the loads which act upon a structure and the forces and stresses which arise within that structure due to those loads, and then designing the structure to successfully support and resist those loads. The loads can be self weight of the structures, other dead load, live loads, moving (wheel) load, wind load, earthquake load, load from temperature change etc. The structural engineer must design structures to be safe for their users and to successfully fulfill the function they are designed for (to be serviceable).
