Abstract:
Civil structure should be economical, durable & stable. Economical structure is a main goal of structure engineer in
recent years. Out of many methods to generate economical structure one method is semi rigidity of connection. By the concept of
semi rigidity, cost optimization can be achieved by transferring desire moment from beam to column or vice -versa. In this concept
cost of connections, beam & column is variable factor & function of semi rigidity. By trial & error method element optimization
can be achieve. The variation of moment, shear force, axial force, displacement and stress is investigated in a selected axis of the
structures. This study reveals that the effect of semi-rigid connections on structural systems shows different variations from
structure to structure. Connection stiffness depends on semi rigidity, material and shape of section.
