全轻混凝土梁承载力研究

Study on carrying capacity of all-lightweight concrete beams

对比分析了同强度等级、相同截面尺寸、不同配筋、不同作用方式的全轻混凝土受弯构件正截面抗弯和斜截面抗剪的承载力研究。通过对11片全轻混凝土梁的试验分析,探讨全轻混凝土应用的可行性及与现有规范的符合性。为实现将全轻混凝土应用于多层建筑结构中,替代多层建筑工程中普通混凝土受弯构件,为轻质节能的多层建筑结构体系提供了理论依据。

It studied the carrying capacity of all lightweight concrete beams, analyzed carrying capacity of cross section bending-resistance and oblique section shear-resistance of bending beam members which have the same level of intensity, the same section size, and different modes of bar configuration, different modes of action comparatively.Through 11 Test analysis, the paper explored the feasibility of all lightweight concrete beams application and the compliance with existing norms, founded some basis that lightweight concrete beams may replace ordinary concrete beams in multi-storey building, and will realize the full light enery-saving multi-storey constructin structures system.
