本文通过正交设计的试验并与无箍梁进行了对比分析,证明箍筋对裂缝的影响显著。文中论述了箍筋对裂缝的影响是由于它对纵向钢筋的钉锚作用引起的。当箍筋间距在一定范围内变化时,梁中设置的箍筋能控制裂缝间距,改善裂缝宽度分布的离散状况。在一定条件下,箍筋的设置能改变裂缝的性质。在上述分析箍筋等因素对裂缝的影响原因和影响规律的基础上,本文提出考虑箍筋等因素的裂缝计算公式。
This article through the orthogonal design of the test and compared with the no-hoop beam to prove that stirrups have a significant impact on the cracks. The article discusses the effect of stirrups on cracks due to its anchoring effect on the longitudinal reinforcement. When the spacing between stirrups varies within a certain range, the stirrups placed in the beam can control the crack spacing and improve the dispersion of crack width distribution. Under certain conditions, the setting of stirrups can change the nature of cracks. Based on the above analysis of factors such as stirrups and their influence on cracks, this paper proposes a crack calculation formula that considers factors such as stirrups.
