It is to understand, predict, and calculate the stability, strength and rigidity of structures.
It is to find out safe and economical specifications for a structure or a member of the structure sufficient to carry the load. It is to develop functional & safe designs and integrate it with that of other designers and with construction at site. Structural engineering design utilizes a number of relatively simple structural elements to build the complex geometry of structures. Structural engineers are responsible for engineering design, structural analysis and integrity of the entire system, and for making creative and efficient use of funds and materials. The complexity of modern structures often requires a great deal of creativity from the engineer in order to ensure the structures support and resist the loads to which they are subjected to.
