木材具有绿色环保、轻质美观等诸多优点,在我国的应用逐渐增多,空间结构是其中一种结构形式。木空间结构主要可以分为木空间网格结构和木空间张拉结构。以一些典型木空间结构为例,综述了木空间结构在形态分析、数值模拟、长期荷载作用下性能、节点研究、可靠性研究等几方面的现状。提出了木空间结构研究需要解决的关键问题,包括材料本构模型的建立与选用、木材在长期荷载作用下的蠕变问题、试验研究和数值模拟方法、结构动力特性和动力响应以及结构体系的可靠性研究等。
Wood with green, light and beautiful and many other advantages, the application of our country is gradually increasing, the spatial structure is one of the structural forms. Wood space structure can be divided into wood space grid structure and wood space tension structure. Taking some typical wood space structures as an example, the current status of wood space structures in several aspects such as shape analysis, numerical simulation, performance under long-term load, node research and reliability research are summarized. The key issues to be solved in the study of wood space structure are proposed, including the establishment and selection of material constitutive model, the creep problem of timber under long-term load, experimental research and numerical simulation methods, structural dynamic characteristics and dynamic response, and structural system Reliability studies.
