摘要: 钢筋混凝土结构是目前房建工程中应用最为广泛的建筑结构，但因混凝土拌制、浇筑及养护不当，极易出现非受力裂缝。本文对某房建工程中一出现非受力裂缝的板类构件，在裂缝未经处理的情况下，通过原位加载试验，以验证其承载能力是否满足设计要求，来确定其结构的安全性。

Abstract: Reinforced concrete structure is the most widely used building structure in housing construction, but due to improper mixing, pouring and maintenance of concrete, it is easy to appear non stress cracks. In this paper, a plate component with non stress cracks in a building project is tested by in-situ loading test to verify whether its bearing capacity meets the design requirements and to determine the safety of its structure.
