【提要】  工程設(shè)計(jì)遇到具有復(fù)雜應(yīng)力場的非彎曲構(gòu)件，如缺口梁、錯(cuò)洞剪力墻等構(gòu)件時(shí)，設(shè)計(jì)人員通常根據(jù)工程經(jīng)驗(yàn)，以構(gòu)造措施保證其抗震性能，然而對(duì)這種構(gòu)造措施的依據(jù)及其適用性缺乏更深入的研究。通過對(duì)拉壓桿模型的介紹，結(jié)合我國現(xiàn)行規(guī)范給出適合我國規(guī)范的拉壓桿模型計(jì)算參數(shù)和設(shè)計(jì)步驟。同時(shí)以錯(cuò)洞剪力墻為例說明利用拉壓桿模型進(jìn)行抗震設(shè)計(jì)的可行性，把結(jié)果和鋼筋混凝土彈塑性有限元分析結(jié)果相比較，說明其優(yōu)點(diǎn)及局限性。給出了若干應(yīng)用拉壓桿模型的設(shè)計(jì)工程實(shí)例，并對(duì)一些常用構(gòu)造措施進(jìn)行了討論。

Application of Strutandtie Model on Reinforced Concrete Member Design/Wu Hui，Liu Weiya （Shenzhen Huasen Architecture & Engineering Design Consultants Ltd.，Shenzhen 518054，China）
Abstract:In engineering practices，designers often use details based on engineering experience to ensure the seismic performance of nonflexural members with complex stress fields，such as beam with dapped end and wall with staggered openings etc，but no further investigations are made on their basis and adaptability. By introducing the strutandtiemodel，the critical factors and design procedures which satisfy Chinese codes requirements are given. As an example，a wall with staggered openings is analyzed using strutandtie model and nonlinear finite element analysis. The comparison of both analytical results is performed to indicate the advantages and limitations of strutandtie model. Finally，some design examples and a discussion on some details are presented.
