［摘要］以墻體高寬比和墻體所受的豎向壓應(yīng)力作為試驗(yàn)的變量，通過擬靜力試驗(yàn)對自動(dòng)砌墻機(jī)所砌出的6片新型企口裝配式砌塊砌體墻的各項(xiàng)抗震性能進(jìn)行研究，包括墻體破壞的過程、最終破壞形態(tài)、抗震承載力、抗剪承載力、耗能性能、延性以及剛度退化特征等。結(jié)果表明:提高墻體的高寬比，會(huì)顯著減小墻體的開裂荷載、最大荷載和破壞荷載。同時(shí)，高寬比的增大會(huì)提高墻體耗能能力和延性。墻體豎向壓應(yīng)力越大，其初始剛度和抗剪承載力會(huì)有明顯的提升，剛度退化的速度逐漸減小，但墻體的耗能能力顯著降低。該類新型企口裝配式砌塊砌體墻的抗震承載力、抗剪承載力滿足規(guī)范和試驗(yàn)擬合公式的要求，具有一定的安全強(qiáng)度儲(chǔ)備，可以在廣大村鎮(zhèn)地區(qū)推廣使用。

Abstract:Taking the aspect ratio and the vertical pressure stress of the wall as the variable of the experiment, the seismic performance of the six new prefabricated interlocking block masonry walls built by the automatic wall-building machine was studied by the static force test, including the process of wall damage, the final destruction form, the seismic carrying force, the shear-resistant carrying force, energy dissipation performance, the ductility and the characteristics of stiffness degradation. The results show that increasing the aspect ratio of the wall will significantly reduce the cracking load of the wall, the maximum load and the destructive load. At the same time, the increase of the aspect ratio can improve the energy dissipation and ductility of the wall. The greater the vertical pressure stress of the wall, the greater its initial stiffness and shear-resistant carrying force will be significantly improved, the rate of stiffness degradation will be gradually reduced, but the energy dissipation performance of the wall will be significantly reduced. This kind of new type of prefabricated interlocking block masonry wall′s seismic carrying force, shear-resistant carrying force meet the requirements of the specification and test fitting formula, with a certain amount of safety strength reserves, and can be popularized in the vast number of villages and towns.
Keywords:new type of prefabricated interlocking block masonry wall;seismic performance;shear-resistance carring force;energy dissipation performance
