【摘要】：輕型木結(jié)構(gòu)具有施工周期短、節(jié)能環(huán)保、宜居性和抗震性能好等優(yōu)點(diǎn),適合于作為我國(guó)村鎮(zhèn)地區(qū)的居民住房使用。但是受限于高昂的造價(jià),輕型木結(jié)構(gòu)難以在我國(guó)的農(nóng)村地區(qū)大面積推廣。我國(guó)的小徑木資源十分豐富,但利用效率低下。為了挖掘小徑木的工程利用價(jià)值,哈爾濱工業(yè)大學(xué)基于輕型木結(jié)構(gòu)體系研發(fā)了小徑木輕型木結(jié)構(gòu)體系。小徑木組合擱柵樓蓋作為小徑木輕型木結(jié)構(gòu)體系中的重要抗側(cè)力構(gòu)件,其受力性能需要加以研究。本文旨在研究小徑木組合擱柵樓蓋面內(nèi)受力性能,并探討樓蓋面內(nèi)剛度對(duì)于剪力墻水平荷載分配的影響。制作了3個(gè)小徑木組合擱柵樓蓋試件,對(duì)試件進(jìn)行了面內(nèi)加載試驗(yàn),分析了樓蓋的面內(nèi)受力性能。制作了20個(gè)覆面板釘連接試件和5個(gè)加強(qiáng)薄鋼帶釘連接試件,對(duì)試件進(jìn)行了抗側(cè)力試驗(yàn),獲得了試件的荷載-滑移曲線,通過對(duì)試驗(yàn)數(shù)據(jù)進(jìn)行擬合獲得了覆面板釘連接和加強(qiáng)薄鋼帶釘連接的工作曲線。利用ABAQUS建立了小徑木組合擱柵樓蓋有限元模型,將有限元模型的計(jì)算結(jié)果和試驗(yàn)結(jié)果進(jìn)行了對(duì)照,驗(yàn)證了有限元模型的正確性。利用小徑木組合擱柵樓蓋有限元模型分進(jìn)行了參數(shù)分析,分別研究了釘連接間距、樓蓋高寬比、橫撐、擱柵間距以及洞口對(duì)樓蓋面內(nèi)受力性能的影響。分別建立了小徑木輕型木結(jié)構(gòu)有限元模型,利用有限元模型分析了樓蓋剛度對(duì)剪力墻水平荷載分配的影響,給出了小徑木輕型木結(jié)構(gòu)房屋剪力墻水平荷載分配系數(shù)的計(jì)算方法。
[Abstract]:The light wood structure has the advantages of short construction period, energy saving and environmental protection, livable property and good seismic performance, etc. It is suitable for the use of residential houses in the villages and towns of our country. However, limited by the high cost, light wood structure is difficult to be widely used in rural areas of our country. The resources of small-diameter wood are very rich in our country, but the utilization efficiency is low. In order to excavate the engineering utilization value of the small diameter wood, Harbin University of Technology developed the light wood structure system based on the light wood structure system. The composite joist floor of small diameter wood is an important lateral force resistant member in the light wood structure system of small diameter wood, and its mechanical properties need to be studied. The purpose of this paper is to study the in-plane mechanical behavior of small diameter wood composite joist floor and to discuss the influence of floor stiffness on horizontal load distribution of shear wall. The in-plane loading tests of three small diameter wood composite joist floor specimens were carried out, and the in-plane mechanical properties of the floor were analyzed. The load-slip curves of the specimens were obtained by the lateral force test of 20 steel strip fastening specimens and 5 reinforced steel strip nailing specimens, and the load-slip curves of the specimens were obtained, and the load and slip curves of the specimens were obtained, and the load slip curves of the specimens were obtained. By fitting the test data, the working curves of the laminated plate nail connection and the reinforced steel strip nail connection are obtained. The finite element model of small diameter wood composite joist floor is established by Abaqus. The calculation results of the finite element model are compared with the experimental results and the correctness of the finite element model is verified. The finite element model of small diameter wood composite joist is used to analyze the parameters, and the influence of the connection distance of nail, the ratio of height to width of floor, the transverse bracing, the spacing of joist and the opening of the tunnel on the mechanical behavior of the floor surface are studied respectively. The finite element model of light wood structure with small diameter wood is established, and the influence of floor stiffness on the horizontal load distribution of shear wall is analyzed by using the finite element model, and the calculation method of horizontal load distribution coefficient of shear wall of light wood structure building with small diameter wood is given.
