基于M-N关系图的RC偏压构件强度设计方法
Strength design method of RC eccentric compression member based on M-N relation diagram
摘要
Abstract
According to the design principles of eccentric compression members in Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridge and Culverts (JTG D62-2004), the specific design method does not limit, so designers have their own room to play. In view of the disadvantages of the conventional design method, which is subjective judgment and isn't suitable for the PC calculation, the connotation of M-N diagram was explored and utilized, and a design method was put forward. In the environment of PC, the dynamic association between reinforcement ratio and M-N diagram was established. The position relationship of the M-N curve and M, N design value were used to reflect the carrying capacity, so as to achieve the design purpose. At the same time, the non-dimensional analysis method was introduced to simplify the calculation process, so that the design essential factor can be compared horizontally. In addition, combined with an example, the exact solution of the reinforcement ratio is given, with the purpose of reflecting the effectiveness of the method.关键词
