    Abstract:

    This paper presented an accurate method of calculating the earthquake force design sensitivity and Hessian matrix of the planar frame. The formulas for the earthquake force design sensitivity and Hessian matrix of the planar frame were deduced based on the finite element method and Newmarkβ method, and the corresponding calculating program was implemented with matlab language. Finally, a twostory planar frame was demonstrated as an example. The results indicate the method is effective.
