摘要
乐山博物院观光塔采用索膜-刚架组合结构的形式,将建筑造型和结构受力较好地结合在一起。索膜-刚架组合结构通过外围的钢框架和内部独立钢柱承担结构的竖向荷载和预应力的竖向分量,风和地震等水平作用则通过周边的索系和内部的索膜结构分担。计算表明,该结构形式具有良好的抵抗侧向作用的能力。
The cable-membrane supported frame is introduced to the design of sighting tower of Leshan museum,which suitably integrates the architecture form and forced structure.The frame and the isolated inner pillar of composite structure support all kinds of vertical loads and the prestress with the same vector.Horizontal loads such as wind and earthquake are carried by peripheral cables and interior cable-membrane structure.The calculation shows that this kind of structure has enough lateral stiffness.
