[提要]  为了研究混凝土空心小砌块建筑中存在的温度裂缝问题，总结了温度应力理论分析的模型，并采用有限元方法对三种不同构造的小型砌块单片墙体进行计算比较，得出各种墙体的最大侧移和应力分布情况，明确了芯柱和构造柱在减小单片墙体侧移、提高混凝土小型砌块墙体抗裂荷载和极限荷载方面的作用，为设计和施工提供参考依据。

In order to resolve the cracking of concrete hollow pint-sized brick building, this paper adopts FEA to analyze diverse constructional details in concrete hollow pint-sized brick wall, from which we can find out the distributions of displacement and stress and the functions of these constructional details to find the best project restricting the wall's displacements and preventing cracking of the walls. Calculated results will be compared with experimentation to find out the best crack-controllig methods, which will provide a lot of reference data for design and construction.
Keywords:  concrete hollow pint-sized brick; temperature crack; finite element analysis; diverse constructional details
