引言木结构组合连接根据材料可分为以下四种:木材与木材、木材与钢材、木材与混凝土、木材与其他材料。木材的顺纹抗压强度大于其顺纹抗拉强度,是一种抗压材料,而钢材作为各向异性材料强度高,制作加工便利,木材与钢材组合结构能充分发挥材料性能,而螺栓连接作为现代木结构一种重要金属连接方式,具有简洁,安装和维修方便,安全可靠等优点。广泛运用于大型现代木结构中,如图1、2。在
INTRODUCTION WOOD STRUCTURAL CONNECTIONS CAN BE DIVIDED INTO THE FOUR OF THE FOLLOWING FOLLOWING MATERIALS: WOOD AND WOOD, WOOD AND STEEL, WOOD AND CONCRETE, WOOD AND OTHER MATERIAL. The parallel grain compressive strength of wood is greater than that of its parallel grain tensile strength, which is a kind of compressive material, while the steel material has high strength as an anisotropic material and is convenient for making and processing. The combined structure of wood and steel can fully exert the material properties, while the bolting As an important modern metal structure of metal connections, with simple, easy installation and maintenance, safe and reliable. Widely used in large modern wood structure, as shown in Figure 1,2. in
