混凝土开裂是制约SRC梁安全性、适用性的关键问题之一,而影响开裂的内在因素比较繁杂,增加了SRC梁裂缝研究的难度。本文将灰色关联方法引入到SRC梁裂缝因素影响分析中,为SRC梁裂缝试验研究提供了一种简便的辅助方法。此外,本文基于灰色关联分析方法,对西安建筑科技大学SRC梁裂缝试验数据进行统计计算,得到了影响SRC梁裂缝宽度的各因素间的顺序关系,计算结果可为SRC梁开裂机理研究及裂缝宽度实用计算方法研究提供一定的参考。
Cracking of concrete is one of the key issues that restrict the safety and applicability of SRC beams. However, the inherent factors that affect cracking are complicated, which makes it more difficult to study SRC beam cracks. In this paper, the gray correlation method is introduced into the SRC beam crack influence analysis, which provides a simple and convenient auxiliary method for SRC beam crack research. In addition, based on the gray relational analysis method, this paper calculates the SRC beam crack test data of Xi’an University of Architecture and Technology, and obtains the order relationship among the factors that affect the SRC beam crack width. The calculation results can be used to study SRC beam cracking mechanism and crack width Practical calculation methods to provide some reference.
