摘要
Abstract
This paper conducts a comprehensive dynamic characteristics analysis of a novel prefabricated grid-type steel-concrete composite roof structure,along with parametric dynamic analysis research based on component specifications and assembly unit dimensions.The results indicate that the thickness of the concrete slab significantly affects the fundamental frequency of the structure,with an optimal range of 1/2 to 3/4 of the structural height to achieve optimal mechanical performance.The vertical leg length of angle steel also exhibits a notable influence on the fundamental frequency,recommended to be 1/20～1/10 of the assembly unit size.Furthermore,the assembly unit dimension significantly impacts the fundamental frequency,with an optimal range of 1.5～2.5 m,corresponding to 1/10～1/6 of the structural span.关键词
