[提要] 新頒布的設(shè)計(jì)規(guī)范將剪力墻邊緣構(gòu)件區(qū)分為約束邊緣構(gòu)件和構(gòu)造邊緣構(gòu)件，兩者的配筋形式及配筋數(shù)量要求均不同，結(jié)構(gòu)設(shè)計(jì)必須在施工圖中準(zhǔn)確反映設(shè)計(jì)規(guī)范的規(guī)定，同時又需考慮設(shè)計(jì)和施工的方便。通過摸索和推敲，給出了剪力墻邊緣構(gòu)件的一種科學(xué)配筋形式，供結(jié)構(gòu)工程師參考。
[關(guān)鍵詞] 邊緣構(gòu)件 體積配箍率 縱向鋼筋 箍筋 間距 肢距According to new design codes published recently, the edge members of shearwall are divided into the restraining edge members and constructional edge members, which are different in reinforced ways and quantity. Structure engineers must obey the regulations of the codes strictly, and need to consider the convenlence of design and construction. Through the practice and refining, a reasonable way is presented to reinforce the edge members, which would be reference for design.
Keywords: edge member; volume ratio of reinforcement; longitudinal reinforcement; stirrup spacing; leg-span
