Multi-Point Input Method of Finite Element Earthquake-Proof Analysis for Long-Span Bridge Structure

Shi ZhiLi  
The paper considers the space interrelation of the earthquake moving yard and study on the earthquake proof analysis method of long span bridge structure under the mode of multipoint input earthquake reaction.The method obtains directly the power spectral values of the response variable of the specific frequency point by the square of the response variable amplitude value.So it can obtain the statistical characteristics such as the mean square values etc.In the comparison with traditional even input method,the increased working volume is not large,but it is more sui table to the engineering practice.
