顶弦,上弦杆
Roof top and facade secondary structure can effectively reduce the out-of-plane calculated length of the primary chords, and provide support conditions for ETFE cladding structure, acoustic ceiling at the bottom chord and roof drainage system, forming the lateral force resisting system for the structure.
屋顶与立面次结构可以有效减小主结构弦杆面外的计算长度,提供ETFE膜结构、下弦声学吊顶与屋面排水系统的支承条件,并形成结构的抗侧力体系。
