钢筋混凝土受弯构件挠度计算方法综述分析

摘要

The principal factors affecting short-time and long-time deflection behavior of reinforced cohcrete flexural members were discussed. The status quo of the calculating theory for deflections of reinforced concrete flexural members was elaborated systematically,and several methods for computing deflection were reviewed. Furthermore, an evaluation of the methods for predicting initial or timedependent deflection was made through the existing beam deflection test data.%讨论了影响钢筋混凝土受弯构件短期挠度和长期挠度的主要因素,系统地阐述了国内外钢筋混凝土受弯构件挠度计算理论的研究现状,综述了受弯构件挠度计算方法.根据国内外对钢筋混凝土受弯构件挠度的试验研究成果,计算并分析了各种短期挠度和长期挠度计算方法的适用性.
