Evaluation Of The Seismic Demand Chord Rotations Of Structural Reinforced Concrete Members

Transcript

In the present article, the calculation of seismic demand chord rotations (elastic and plastic) of structural reinforced concrete (r/c) members, without using various inelastic springs at their ends, is analytically developed. Particularly, in order to calculate, in the nonlinear area, the seismic demand chord rotations of structural r/c members, the following three cases must be examined separately: (1) Exterior roof joint of single-storey frame, (2) interior roof joint of single-storey frame and (3) exterior & interior floor joint of multi-storey frame. The above-mentioned three cases consist the theoretical base for the calculation of the seismic demand chord rotations of r/c members of each other case. This presentation is very useful for the develop of suitable software about the seismic nonlinear (static/dynamic) structural analysis without using nonlinear springs.
