| 摘 要： | 通过低周反复荷载试验揭示了短肢墙从弹性应力状态到砼开裂、钢筋屈服、直至结构破坏的全过程.试体分为两组,无翼墙与有翼墙各一组,结果表明:当无翼墙试体墙肢较短时,墙肢底部纵筋首先屈服;墙肢较长时,连梁箍筋首先屈服.有翼墙试体无论肢厚比大小,均在墙肢和翼墙底部纵筋处首先屈服.从强度和耗能能力来看,肢厚比在6.5左右时,结构的综合性能较好.

| Abstract: | The horizontal cyclic loading tests on SLW structures manifest the whole process from elastic to plastic, until concrete crush. The specimens are divided into two groups: one with flanged wall and the other without. The results denote that for non flanged SLW, when the limb is shallow, the longitudinal bar in the limb will firstly yield; on the other hand, when the limb is deep, the stirrup in the linking beam will firstly yield. For the flanged SLW, the longitudinal bar in the limb or flange will firstly yield no matter what value the ratios are. From the point of view of load bearing capacity and energy dissipating, when the ratio is 6.5, the specimens have the best behaviors. |
