Project Name：The Performing Arts Center of Tianjin Happy Valley Project Location：Tianjin Diameter：85 m2 Construction Unit：Shanghai Zhenyuan Timber Structures Engineering Co., Ltd. (ZY Timber) Category：Tourism Project Brief： The project is a single-layer spherical reticulated shell with a timber structure, with a design service life of 50 years. The safety grade of the building structure is level 2, and the anti-seismic grade is 7. The external framework is designed to apply glulam structure with a vault. The spherical radius is 57m.The height of chord is 19m, and the bottom diameter of the wooden dome is 85m. It is supported by 6-meter-high concrete columns (and concrete ring beam). The wooden dome is connected to the concrete foundation with pin-joint, and the other joints use rigid joint. The width of a single piece of glulam is more than 1m, and the site hoisting also needs a lot of experience. The V-shaped hoisting is used to solve the difficult problem. According to the 85-meter diameter circular 30 equal design, the lateral support of the glulam component is provided by the main keel of the glass curtain wall. The keel spacing is about 1.5 m between the timber members. |
