It has been undertaken here to use the matrix method of
structural analysis for the determination of the stability of elastically
restrained, simple portal frames. This involves the formulation of
the stiffness matrix of the structure in terms of the axial force in the
members. The stability criterion, when applied...
There are several factors which affect the cost and efficiency
of a structure. The most important and basic factors are: the predominant
stress, the way the structure carries the loads and the
shape of the structure.
The structures in which the predominant stress is not bending
have been chosen to...
Structural design codes have evolved continuously since modern codes were established. The allowable stress design format has been widely used since the late 191h century. During the past two decades, probability-based limit states design concepts have evolved and are increasingly being used for various material and structural types. Limit state...
