钢丝绳网栅顶结构的承载能力分析

摘要

The idea of technological transplantation was used to apply the technological principle of steel wire grids protection to the grid design of auditorium so as to succeed in completing the steel wire grid structure of multifunctional hall. By means of theoretical and FEM analysis its loading property and bearing state were taken into account to reveal itsdeformingandstressdistributionunderthedifferentworkingconditionssoastoprovidequantitativereferencefor analysisofitsloadingabilityandcommentonitssecurity.Thepracticalexampleofresearchanddesignshowedthat thestructurehasalotofadvantages,whichwerelightinweight,stronginbearingability,flexibleinarrangementand convenient in construction. With the reasonable analysis and optimizing design, the structure of steel wire grids can replace that of the rigid grids.%采用技术移植理念，将钢丝绳网防护系统的技术原理应用于演出厅堂的栅顶设计，成功实现多功能厅钢丝绳网栅顶结构。通过理论分析和有限元模拟方法考虑其载荷特点及承载状况，揭示其在多种使用工况下的变形和内力应力分布，为其承载能力分析和安全可靠性评价提供了定量依据。研究和设计实例表明：钢丝绳网栅顶结构具有重量轻、承载能力大、布置灵活、施工方便等优点，经过合理的分析和设计，可以替代刚性栅顶结构。
