Abstract


At home and abroad for the Tibetan architecture is mainly in terms of its architectural style , decorative arts , and religious significance , very little analysis of its structure and properties . Crowd of Tibetan ancient architectural structures load static and dynamic test based on the crowd load structure , and to assess the structural floor vibration comfort , establish such structure finite element model . Mainly includes the following aspects : the site inspection on the basis of three from the Tibetan building materials , ministries practice structure a comprehensive exposition of the structural characteristics of Tibetan architecture to provide a basis for the establishment of a numerical model . 2 . Crowd on a typical Tibetan ancient structure static and dynamic test . Static crowd load based on the test results , the mutual influence between the floor and the population density of the structural response . For the the dynamic crowd load walking and running two types of activities : based on walking load displacement curves obtained structural floor vertical vibration frequency and damping ratio ; Statistics walking and running load structure acceleration time curve by which to assess floor vertical vibration comfort ; simultaneous analysis the dynamic crowd load , the interaction between the floor and the population density of structural response ; walking and jogging load structure acceleration response by comparing a different type of crowd activities the impact of structural vibration . Using ANSYS finite element model of the test structure , the comparative test results with the results of the finite element model to determine a more reasonable finite element modeling , and provide a basis for the numerical analysis of Tibetan cloister structure . 4 of the finite element model of the Tibetan cloister floor comfort evaluation based status quo crowd routes and the distribution density ; crowd load of the structure may occur the most adverse circumstances , estimates the vibration comfort level structure in dangerous conditions .
