[提要]  通过对设和不设圈梁及构造柱的两种砌体结构模型进行试验，并应用ANSYS软件对其进行理论分析，研究圈梁及构造柱对砌体结构现浇楼板非荷载裂缝的影响，得出一些有益的结论。
[关键词]  砌体结构  现浇楼板  约束刚度  裂缝

Through the experiment of two types of masonry structure models, one includes collar beams and constructional pillars, the other does not, and using ANSYS software to analyse it theoretically, the influence of collar beams and constructional pillars on the non-loaded cracks in the cast-in-place RC slabs of the masonry structures is researched, and gets some useful conclusions for engineering.
Keywords: masonry structure; cast-in-place RC slab; restraining stiffness; crack
