Experimental And Numerical Analysis Of Anti-seismic Performance Research On China Dinosaur Pagoda

The China Dinosaur Pagoda will be built in Jiayin County Dinosaur Geological Park, Heilongjiang Province. It is the highest overrun unreinforced buildings of stone structure in China modern time when completed. Masonry pagoda is a kind of outstanding representative of ancient high-rise buildings and architectural art treasures, which has excellent seismic performance and stands down for thousands of years. The China Dinosaur Pagoda is modeled on the antique stone pagoda building. It is the national media to develop Chinese architectural style of ancient characteristics, continue the important content of building structures, and fill the blank of the stone structure of the tower on the new design and the seismic properties, which has important theoretical significance and engineering value.The study on the technology investigation of prototype pagoda is to analysis its present situation after earthquake and damage, making structural design on the China Dinosaur Pagoda. Thus starting a 1/12 model shaking table test, in combination with effective numerical simulation based on finite element method on the model and full scale of the China Dinosaur Pagoda, researching its dynamic properties and seismic responses. What have done above is to conclude comprehensive evaluation of resisting seismic capacity and construction feasibility on China Dinosaur Pagoda.This paper introduces the model shaking table test design, construction and test conditions and procedures of the China Dinosaur Pagoda structure, and analyses the test results. This research observes the weaknesses and failure mechanism and studies the dynamic properties of the model and seismic response under earthquake. The results indicate that the model structure has a good seismic performance in the elastic range, there is no obvious weak layer in this structure and it can meet the current specification requirements to resist seismic.A simplified model similar to shaking table tests is established by commercial finite element software SAP2000. The dynamic characteristics and structural seismic response are obtained by the spectrum method, elastic time history analysis, respectively. The finite element analysis results are agreed with the experimental results.This research calculates the gravity and seismic performance on the Chinese Dinosaur Pagoda by SAP2000. The dynamic characteristics are obtained from modal analysis and the dynamic responses on the China Dinosaur Pagoda are calculated by the modal response spectrum method and the elastic time history analysis method. It is concluded that the structure meets the opportunities and the equivalent of more than 6 degrees fortified targets, when the design base period is 100 years, with the equivalent of 6 degrees rare earthquake design basis corresponding to a period of 50 years 9 multi-degree earthquake, the structure is safe. The structural elastic calculating cannot meet the capacity design requirements when encounter the rare earthquake of 7 degrees.
