IDENTIFICATION AND MODIFICATION OF FRAME STRUCTURE
The paper presents identification and upgrade of structure under earthquake loads on the base of optimization.The measured frequency spectrum of the structure determines the numerical model design. The structure is excited by ground acceleration. Linear and nonlinear dynamic analysis in time domain is realized.The identification of the model parameter is solved as an optimization problem. The objective is the error index minimization between measured response in real structure and calculated response of the numerical model. The hybrid optimization algorithm is applied.In order to improve earthquake resistance of the structure the passive control with help of tuned mass damper is designed.Three-storey frame is investigated. Experimental and parallel numerical analyses are realized. Accelerograms from the Friuly-earthquake are applied.
