［摘要］根據(jù)《混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范》（GB 50010—2010）及《高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程》（JGJ 3—2010）的有關(guān)計(jì)算公式，論述了矩形截面剪力墻邊緣構(gòu)件縱向鋼筋配筋面積的計(jì)算方法。得出了邊緣構(gòu)件縱向鋼筋面積當(dāng)由承載力控制時(shí)，邊緣構(gòu)件的縱向配筋應(yīng)考慮分布鋼筋的影響。實(shí)際工程中，剪力墻為偏心受壓時(shí)一般為構(gòu)造配筋；對于偏心受拉剪力墻墻肢，特別是長墻肢構(gòu)件，集中配置在邊緣構(gòu)件內(nèi)的縱向鋼筋應(yīng)為計(jì)算面積與邊緣構(gòu)件范圍內(nèi)的分布筋面積的一半之和。

Abstract: According to the related formulas of Code for design of concrete structures （GB 50010—2010） and Technical specification for concrete structures of tall building （JGJ 3—2010）, the calculation method of the longitudinal reinforcement area of shear wall′s boundary elements with rectangular section was discussed. And draws a conclusion that when the longitudinal reinforcement area of boundary elements is controlled by bearing capacity, the influence of distributed reinforcement should be considered. In actual projects, eccentric compression shear walls are generally designed as constructional reinforcement; for eccentric tension shear walls, especially long-limbed walls, the longitudinal reinforcement area in boundary elements should be the sum of its calculating area and half of the distributed reinforcement area in the range of boundary elements.
Keywords: shear wall; distributed reinforcement; boundary element; eccentric compression; eccentric tension
