Abstract

In ranges with negative moments, crack formation influences the structural behavior of statically indeterminate composite beams under service conditions. Composite beams with partial-depth precast concrete units show some particularities, which cannot be described accurately using the established methods of calculation. This article presents methods of calculation, which can be used to cover the specific structural behavior and describe crack formation, crack widths and deformations realistically.

部分深度预制混凝土单元组合梁的裂缝与变形行为
在负弯矩范围内,裂缝的形成会影响超静定组合梁在使用条件下的结构性能。部分深度预制混凝土单元组合梁具有一定的特殊性,用现有的计算方法无法准确描述。本文提出的计算方法,可用于涵盖具体的结构行为,并能真实地描述裂缝的形成、裂缝宽度和变形。
