Analysis Of The Simply Supported Continuous Rigid Frame Bridge Seismic Response

With the development of transportation in our country, the simply supported continuous rigid frame bridge is used in the field of bridge construction. Simply supported continuous rigid frame bridge with continuous performance good, telescopic less joint structure, can provide high speed driving conditions, smooth, comfortable. Simply supported continuous rigid frame structure, dynamic properties, seismic response of structure will have great changes, in order to ensure the simply supported continuous rigid frame bridge under earthquake safe and reliable operation, to avoid the earthquake occurred when the earthquake casualties, reduce economic losses caused by, turning on the simply supported continuous rigid frame bridge seismic response analysis there is very important significance.In this paper the basic theory foundation in the seismic response analysis of continuous rigid frame bridge, turn to the simply supported seismic response analysis: the main research contents are as follows:1, to Shi Jia Gou Bridge and Redcliffe Gou Bridge as the project background, according to different pier girder connection, the dynamic characteristics of the establishment of dynamic calculation model and the calculation of each model;2, standard response spectrum analysis and time history response analysis on each model;3, through the comparison of calculation results, the model response under seismic action, and focuses on the analysis of earthquake response of simply supported continuous rigid frame bridge.With the development of transgenic research work of continuous rigid frame bridge with simply supported deep, after simply supported further application of continuous rigid frame bridge will provide more rich theoretical results, so as to produce more social benefit and economic benefit.
