［摘要］基于室內(nèi)1∶3縮尺夯土墻的低周反復(fù)荷載試驗(yàn)，采用ABAQUS有限元軟件對(duì)采用不同構(gòu)造措施的夯土墻進(jìn)行數(shù)值模擬，對(duì)比分析了不同構(gòu)造措施夯土墻的水平承載能力、變形能力等抗震性能的提高程度。結(jié)果表明，在夯土墻體中設(shè)置一定的構(gòu)造措施可以改善墻體的受力特性，增強(qiáng)墻體的變形性能和耗能能力，提高墻體的抗震性能。在保證墻體抗屈服和抗剪能力不減弱的情況下，考慮施工繁簡(jiǎn)和成本，建議優(yōu)先選擇設(shè)置混凝土構(gòu)造柱和三道拉結(jié)筋的夯土墻作為承重墻體。

Abstract:Based on the indoor low cyclic reversed loading test of 1∶3 scale rammed earth wall, the rammed earth wall with different construction measures was used to numerical simulation by ABAQUS finite element software, and the degree of improvement in seismic performance such as the horizontal bearing capacity and deformation capacity of rammed earth wall with different construction measures were compared and analyzed. The results show that setting certain structural measures in the rammed earth wall can improve the force characteristics of the wall, enhance the deformation performance and energy dissipation capacity of the wall, and improve the seismic performance of the wall. Under the circumstance of ensuring that the yield resistance and shear resistance of the wall are not weakened, considering the complexity and cost of construction, it is recommended that the rammed earth wall with concrete structural columns and three tie bars should be selected as the load-bearing wall.

Keywords:rammed earth wall; low cyclic reversed loading; structural measure; force characteristics; numerical simulation; seismic performance
