Application of Internal Force Analysis of Plastic Deformation in Structural Members to Engineering Design

摘要

The internal force analysis for reinforced-concrete structural members is calculated mostly according to the elasticity approach, which increases the amount of reinforcement. The present experiment reveals that if the calculation approach, in which the internal force redistribution after the formation of plastic hinges is taken into consideration and the internal force in a structure is determined through the internal and external equilibrium by the time the structure is about to form a geometric variable system, is applied, members will stay in a balanced-reinforced state to meet the safety requirements. This approach can also help to make full use of the material potential and to obtain better economic benefits during project construction.
