［摘要］木框架剪力墻是輕型木結(jié)構(gòu)抵抗側(cè)向荷載的重要構(gòu)件，與頂梁板相連的荷載傳遞梁剛度對木框架剪力墻的抗側(cè)力性能以及破壞模式有直接影響，當(dāng)木框架剪力墻墻端以及墻中洞口邊未采用墻端錨栓時(shí)，這種影響更甚。采用一種新型的、位于頂梁板側(cè)邊的荷載傳遞梁對木框架剪力墻進(jìn)行加載，通過對12片不同構(gòu)造木框架剪力墻的側(cè)向加載試驗(yàn)，研究了木結(jié)構(gòu)單片剪力墻在無豎向荷載作用下的破壞模式、荷載\|位移曲線、彈性抗側(cè)剛度、抗剪強(qiáng)度、極限位移等性能。并對不同構(gòu)造下木框架剪力墻試驗(yàn)結(jié)果進(jìn)行對比分析，認(rèn)為墻骨柱間距的改變對墻體受力性能有較大影響，而釘間距的改變對墻體受力性能影響不大。［關(guān)鍵詞］木框架剪力墻; 受力性能; 構(gòu)造中圖分類號：TU366.2 文獻(xiàn)標(biāo)識碼：A文章編號：1002-848X(2015)22-0097-05
Test research on mechanism performances of wood frame shear walls with different detailsLiu Yan, Wang Honghe, Sheng Xiangqian, Hao Jun, Gao Xiang（College of Civil Engineering, Yangzhou University, Yangzhou 225127, China）Abstract: Wood frame shear wall is commonly used as the primary component in light wood structures to resist the lateral loads. The stiffness of the beam connected with slabs for load transmission has a direct impact on the lateral resistance and failure mode of wood frame shear walls. Furthermore, the effect is greater when hold-downs are not fixed at the ends of the walls and openings. The wood frame shear wall was loaded by a new load transmission beam which was located in the lateral side of the slab. Through lateral loading test studies on 12 wood frame shear walls with different details, performances of the single piece wood structure shear walls without vertical loads were studied, including failure mode, load-displacement curve, elastic lateral stiffness, shear strength and ultimate displacement. Test results of wood frame shear walls with different details were compared and analyzed. It is concluded that wall column spacing has great impact on the mechanical properties of the wall while nail spacing has little impact.Keywords: wood frame shear wall; mechanism performance; detail
