摘要

自支撑竹结构是采用竹圆杆、拉伸受电弓网格和纺织膜的超轻型建筑模块。结构系统在聚酯绳和锁定生物复合绷带环中应用铰接式柔性关节，使竹竿免受扭转应力。制作了一个1:3比例的实验原型和一个全尺寸结构，对结构的物理力学行为进行了预测。应用数值模型对实验结果进行了验证。然后，对柔性关节进行了理论分析。采用SAP2000有限元程序对计算机模型进行了分析。数值计算结果与实验结果吻合较好，特别是对柔性接头的结构特性。

Analysis of a self-supporting bamboo structure with flexible joints

Self-supporting bamboo structures are ultralight architectural modules applying bamboo round poles, tensile pantographic grids and textile membranes. The structural system applies articulated flexible joints in polyester ropes and locking bio-composite bandage rings, keeping bamboo bars free of torsion stresses. An experimental 1:3 scale prototype and a full-scale structure were fabricated to make previsions about the physical and mechanical behavior of the structure. The experimental results were verified applying a numerical model for the structure. In turn, the flexible joints were analyzed theoretically. The computer model was analyzed using the finite element SAP2000 program. The numerical results were in close agreement with the experimental results specifically for the structural behavior of the flexible joints.

期刊介绍： The aim of the journal is to provide an international forum for the interchange of information on all aspects of analysis, design and construction of space structures. The scope of the journal encompasses structures such as single-, double- and multi-layer grids, barrel vaults, domes, towers, folded plates, radar dishes, tensegrity structures, stressed skin assemblies, foldable structures, pneumatic systems and cable arrangements. No limitation on the type of material is imposed and the scope includes structures constructed in steel, aluminium, timber, concrete, plastics, paperboard and fabric.
