［摘要］根據(jù)工程實(shí)例，提出了凹槽式伸縮縫結(jié)構(gòu)設(shè)計(jì)。整體結(jié)構(gòu)劃分為3個(gè)單元，每個(gè)結(jié)構(gòu)單元內(nèi)部采用了凹槽式伸縮縫的處理，并對(duì)該措施進(jìn)行了一定的理論分析與構(gòu)造研究。分析表明，凹槽式伸縮縫的設(shè)置，既保證了單元的側(cè)向剛度，又降低了溫度應(yīng)力，獲得了良好的設(shè)計(jì)效果。

［關(guān)鍵詞］凹槽式伸縮縫；?超長(zhǎng)結(jié)構(gòu)；?溫度應(yīng)力

Design of control joint structure

Zhang Jian, Liu Guiran(Shanghai Institute of Architecture Design and Research, Shanghai 200041，China)

Abstract:The control joint structure was presented based on the concrete project. The whole structure was divided into 3 structural elements, and the control joint was used within each element. Both theoretical analysis and configuration research were conducted. It is found that the control joint structure can provide high lateral stiffness and reduce the temperature stress effectively.

Keywords:control joint; super long structure; temperature stress
