摘要:
为了研究土与结构相互作用对砖石古塔动态特性计算结果的影响规律,建立是否考虑土与结构相互作用时西安小雁塔的数值分析模型,计算了小雁塔的前2阶振型及周期,并将理论计算结果与实测结果进行比较。结果表明:采用理论计算法与数值分析法计算砖石古塔的动态特性时,第1阶周期的计算结果均与实测结果较为接近; 第2阶周期的计算结果均与实测结果偏差较大,在考虑土与结构相互作用时,数值计算结果与实测结果偏差反而加大; 土与结构相互作用对砖石古塔高阶振型的计算结果影响显著。
Abstract:
To study the influence of co-interaction of soil and structures on dynamical characters of masonry pagodas, the numerical analysis model of Xiaoyan Tower in Xi'an was established based on either considering co-interaction of soil and structure or without considering co-interaction. The first two vibration modes and periods were calculated. The theoretical calculation results were also contrasted with measured test results.Results show that the first period of the masonry pagoda by calculation result is close to that of measured test result when dynamical characteristics of masonry pagodas are calculated by theoretical calculation method and numerical analysis method. The second period is widely from the test. Moreover, the result that includes co-interaction of soil and structure is widely greatly. Therefore, the impacts of co-interaction of soil and structure to high vibration modes of masonry pagodas on calculation results are heavily.
