structural cracks

Reinforced concrete structural pillar make use of control of residence roof temperature cracks

砼构造柱在砖混住宅楼顶层墙体温度裂缝控制中的应用

This is due to restrictions on the sudden through of the main cracks in horizontal reinforced bar, when the horizontal reinforced bar yield, furthermore increased the displacement, constraint on the structural column was fully played.

这是由于水平钢筋限制了主裂缝的突然贯通，当水平钢筋屈服后，位移才进一步增大，对构造柱的约束作用才充分发挥。

Impacts may create undetectable cracks that, because of the continuous loads, could result in structural damage.

由于长期使用, 可能会导致结构损坏,从而导致隐患的出现.

According to the wall testing process, we put finite element numerical simulation on the cavity wall which is set the ring beam but without structural concrete column, using discrete model to analysis the principal stress, cracks distribution and displacement of the wall.

参照墙体试验过程，对设置圈梁但无混凝土构造柱的空斗墙体进行有限元数值模拟，采用分离式模型对墙体的主应力、裂缝分布与墙顶位移变化进行分析。

Based on the observed data of the contact cracks at the crown and abutment of the reinforcement and using the theories of structural mechanics, layer finite element, hydraulic structure and mathematical statistics, the actual working state of the contact cracks is studied.

本文根据佛子岭连拱坝加强拱的拱冠拱端接触缝的实测资料，应用结构力学、夹层有限元、水工专业和数理统计等有关理论，研究分析了加强拱接触缝的实际工作状态。
