摘要
幕墙多用作高层建筑的外围护结构,其安全性至关重要,特别是在遭受外力冲击时,幕墙的响应特性及其对撞击的承受能力成为关乎建筑安全的重要因素.通过数值模拟与试验验证相结合的方法,对现代建筑幕墙的耐撞击性能进行了研究.通过建立幕墙的精细有限元模型,模拟了幕墙在不同冲击条件下的变形和应力分布,并通过试验,验证了数值模拟结果的准确性,为幕墙的优化设计和安全评估提供了重要的理论依据和技术支持.
Abstract
The safety of curtain wall is very important,especially when it is subjected to external impact,the response characteristics of curtain wall and its impact resistance become an important factor of building safety.Through the method of combining numerical simulation with experimental verification,the impact resistance of modern building curtain wall is studied.By establishing a fine finite element model of curtain wall,the deformation and stress distribution of curtain wall under different impact conditions are simulated in detail.The accuracy of the numerical simulation results is verified by experiments,which provides important theoretical basis and technical support for the optimization design and safety evaluation of the curtain wall.
