砖混结构的温度裂缝及结构设计

对砖混结构顶层墙裂缝现象作了简要分析，特别分析了裂缝开裂时的受力状况，提出了裂缝产生的原因。提供了在结构设计中采取的构造措施，针对结构设计中存在的问题，对不同部位的加强，构件的布置，墙体的作法都采取了不同的构造措施，这对于在结构设计中能避免产生温度裂缝提供了参考资料。通过在许多砖混结构设计中的运用，达到了控制裂缝产生的目的。

Temperature crack and structural design of brick and concrete structure

The top wall crack phenomenon in brick and concrete structure is analy zed in brief, especially about the stress when the crack is split, and the reaso n of crack producing is put forward. The structural measures in the structure d e sign is given, it's found that different structure measures should be taken on t he strength of different location, the layout of structure and the method of sam ple making according to the existing problems in the structure design. It prov i des reference data on how to avoid temperature crack in structure design, and ac hieves the purpose to prevent the crack from producing through the application i n many brick and concrete structure design.
