摘要

提要:密肋壁板结构中多种材料及构件的使用与嵌套,使实体计算模型比较复杂,在结构计算中需要提出简化计算模型。结合课题组前期研究成果及现代高层结构计算理论,提出密肋壁板结构弹性阶段简化数值模型与解析模型。利用前期1/10比例振动台试验研究结果,采用刚架-复合弹性板模型对结构进行时程分析,并验证简化数值模型的正确性;利用解析模型和数值模型对实际工程进行对比分析,验证解析模型的合理性。理论与试验表明:采用刚架-复合弹性板模型作为密肋壁板结构在弹性阶段的数值模型具有一定的理论依据和可行性;提出的框架-复合墙模型作为密肋壁板结构在弹性阶段的解析模型较为合理,为实际工程提供了一种较为简化、实用的手算解析方法。

Abstract

Abstract: The multi-ribbed slab structure uses various materials and components nesting each other, which makes the entities calculation model extremely complicated, therefore, it is necessary to present the simplified calculation model of the structure.. Based on previous study and the calculation theory of modern high-rise structure , the simplified numerical model and analytical model of multi-ribbed slab structure in elastic stage are presented. According to the previous results of shaking table test on a 1/10 scaled model, the rigid frame-composite elastic plate model is employed to perform the time-history analysis, therefore, the validity of the model is verified. In addition, the comparative analysis of simplified numerical model and analytical model in practical engineering is carried out to verify the rationality of analytical model. Theoretical researches and experimental analysis show that it is not only supported by theory but also useful for practice to adopt the rigid frame-composite elastic plate model as the numerical model in elastic stage, and it is more reasonable to take the frame-composite wall model as the simplified analytical model in elastic stage ,which provides a more simplified and practical hand-calculation method for practical engineering.
