Abstract
Glulam is a kind of environmentally-friendly material with characteristics of multi-functionality and desirable appearance, so it has been widely used for the construction of both simple portal frames and complicated spatial structures. In recent years, due to the market demand for green building and the large span and open space of spatial structure, glulam as the main bearing components have gained more and more attention and applications in China. This paper presents the design of a spatial glulam recreation center which is located in Qingdao, Shandong province, China. It is a single-storey building with construction area of 2250m2. The main structure is composed of glulam slab, two-way prestressed steel cable, glulam bracing rod and round tapered glulam column without extra beams to support the roof. Finite element software SAP2000 was used to simulate and analysis the overall structure. Taking column and steel cable for examples, the design of structural componets and the configuration of the relevant connections are introduced. Results showed that the timber members were primarily controlled by compressive stress, so the advantage of wood under compression can be effectively achieved. Both glulam and steel members have sufficient strength, and the entire structure is safe and reliable.
