[摘要]通過5片磚混教學(xué)樓縱向窗間墻試件的擬靜力試驗,分別對配置不同尺寸和不同配筋率構(gòu)造柱的窗間墻試件的破壞形態(tài)、滯回性能、變形能力等進行了試驗分析。研究結(jié)果表明,構(gòu)造柱的尺寸和配筋率對窗間墻的抗震性能影響較大,增大構(gòu)造柱截面尺寸但保持較低的配筋率可顯著改善窗間墻的抗震性能,但構(gòu)造柱配筋增大到一定程度后反而會降低窗間墻的變形能力。因此,適度增大構(gòu)造柱尺寸并合理控制配筋率是磚混教學(xué)樓縱向窗間墻抗震設(shè)計的關(guān)鍵。

Abstract: Quasi-static tests on five specimens were conducted to investigate the seismic performance of longitudinal wall between windows of brick-concrete school building. The seismic performance of longitudinal wall between windows with different size and reinforcement ratio of structural column was investigated respectively, including damage characteristics, hysteresis behavior and deformation capacity of specimens. The results indicate that the section size and reinforcement ratio of structural column have significant effect on the seismic performance of specimens. Increasing the section size of structural column can improve the seismic performance of longitudinal wall between windows significantly. However, increasing reinforcement ratio of structural column to a certain extent will decrease deformation capacity of longitudinal wall between windows. Therefore, properly increasing the section size of structural column and reasonably controlling the reinforcement ratio are crucial important in the seismic design of longitudinal wall between windows of brick-concrete school building.
Keywords: brick-concrete school building; longitudinal wall between windows; structural column; section size; reinforcement ratio
