一、引言单层高框架结构在一些工程中,比如在高空间厂房、中小型水电站等建筑物,应用比较普遍。该结构的抗震设计有其特殊性。我们应用激光全息干涉法进行了钢架式水电站厂房、重力坝和240m高拱坝等建筑物的自振特性的研究,并与动有限元法相法合对高拱坝结构动应力进行了分析研究。将这种方法应用于单层高框架结构厂房的自振特性研究是一种新的尝试。
I. INTRODUCTION Single-storey high-rise frame structure In some projects, such as buildings in high-space plants, small and medium sized hydropower stations, the application is more common. The seismic design of the structure has its own particularity. In this paper, we study the natural vibration characteristics of buildings such as steel-framed hydropower station, gravity dam and 240m high arch dam by laser holographic interferometry and analyze the dynamic stress of the high arch dam with the dynamic finite element method . It is a new attempt to apply this method to study the natural vibration characteristics of a single storey high-rise building.
