工业生产的叠层竹板是一种新型的环保材料，用于建筑行业的胶合结构。这种类型的面板可以进一步冷胶，以不同的取向组合，形成各种类型的胶合结构元件，以满足不同的结构和建筑要求。轻型钢板框架结构是钢板结构的一种流行形式，它可以在工厂生产和现场安装，很少的劳动力和运输设备，使其在城市或农村地区广泛应用的潜在可能。与轻量化木结构一样，决定轻量化木结构侧抗能力的控制结构单元是框架剪力墙，而剪力墙的侧抗强度是通过所使用的金属连接来决定的。因此，本研究的重点是厚条形胶合竹板轻质钢板剪力墙连接系统的性能，连接系统分别包括板-框架钉连接、框架-框架连接和压紧装置。根据ASTM F1575标准，试验得到了轻质胶合结构用钉的屈服弯矩和屈服曲线。按照ASTM D1761标准进行了不同钉接方式的板-框架连接和框架-框架连接的单调和循环加载试验。得到力学参数（如弹性刚度、最大力efmax、极限位移Δu）。在单调和循环荷载作用下进行了两种不同承载力的压紧连接试验。通过前人的文献研究，验证了基于金属连接信息的轻量化剪力墙有限元模型，并用于预测各种连接和螺栓组合的轻量化框架剪力墙的性能，找到符合一定承载和变形要求的钢筋或木筋混合剪力墙类型。
Industrial-produced laminated bamboo panel is a new type of eco-friendly material used for glubam structures in construction industry. This type of panel can be further cold-glued with different orientation combinations to form various types of glubam structural elements and to meet different structural and architectural requirements. The lightweight glubam frame structure is one of the popular forms of glubam structures which can be produced in factory and installed on site with few labor forces and transportation equipment, making it potentially possible to be widely used in urban or rural areas. Like the lightweight wood-frame structures, the governing structural element determining the lateral resistance capacity of lightweight glubam structures is the frame shear wall, as well as that the shear wall’s lateral resistance strength is determined through the metal connections used. Thus, this study is focused on the performance of connection system used in lightweight glubam shear walls made with thick strip ply-bamboo boards, the connection system includes panel-frame nail connections, frame-frame connections and hold-down devices, respectively. Yield moment and curves of nails used in lightweight glubam structures were experimentally obtained according to ASTM F1575 standard. The monotonic and cyclic loading tests of panel-frame connections and frame-frame connections with different nail connectors were performed following ASTM D1761 standard. Mechanical parameters (such as elastic stiffnesske, maximum forceFmax, ultimate displacement Δu) are obtained. Tests of hold-down connection with two different capacities under monotonic and cyclic loading are also presented in this research. A finite element model of lightweight shear wall based on metal connections information is validated through previous research in literature, and is used to predict the performance of lightweight frame shear walls with various combination of connections and studs, to find a suitable type of glubam or timber-glubam hybrid shear wall corresponding to certain load bearing and deformation requirements.
