Recent decade has witnessed the improvement of performance-based earthquake engineering (PBEE) methods. Therefore, procedures to estimate performance levels of structures have developed in accuracy as well as simplification ...

Reinforced concrete beams are widely used for transmitting electric power in urban

environment in some countries like IRAN. In this paper, one kind of these RC beams

are investigated and optimized. The available ...

Purpose – The aim of this paper is to develop a new method for finding multiple bifurcation points

in structures.

Design/methodology/approach – A brief review of nonlinear analysis is presented. A ...

Four systematic approaches are developed in the context of the indirect methods for

analyzing the nonlinear prebuckling behavior. In this study, an appropriate test function

to monitor bypassing of the critical ...
