叠合箱受弯性能的试验研究与分析

Experimental Study and Analysis on Behavior of Concrete Composite Box Bending Resistance

混凝土叠合箱网梁楼盖是一种新型的楼盖形式,是由小型预制构件(混凝土叠合箱)与现浇混凝土肋梁结合成具有连续箱型截面的整体结构。本文通过对网梁楼盖的3块构件进行抗弯性能试验,得到了楼盖在受弯时的破坏机理,给出了截面抗弯承载力计算方法,为此种新的构件形式的工程应用提供了依据。

The concrete composite box net joint floor is one kind of new-style floor. It is composed of the small prefabricated component with the cast-in-place concrete rib beam.This article described the experiment about the bending resistance and got the failure mechanism on the three components of concrete composite box net joint floor, Through analysing the load-deflection curve and load-tensile stress curve, we got the entity of the concrete composite box net joint floor, and this can supply bases gist for the engineering applications.
