关于地震区框架梁正截面强度计算问题的探讨

本文根据国家标准《建筑抗震设计规范》和近年来结构试验资料,对框架梁在不同设计阶段工作情况进行了分析,提出了承受均布荷载情况下,梁端按双筋截面计算的方法。该法计算简便,既可节约钢材,又能保证强度,可供工程技术人员参考。

Discussion of Computatipn of Strength for Cross Section of Frame Beams Concerning Earthquake Zone

This paper was based on the national standards' Designed Specification of Building Earthquake Resistance' and the experimental data of the recent structures, and was made on the analysis of working cases for the frame beams in the different desgned stages, therefore, the computational method can be put forward by using the double reinforced sections in the beam ends under the circumstance of bearing the distributional load. this method is simple to calculation and save steel materials, and also ensure the strngth. It can be used for reference in design.
