The paper deals with the analysis of chosen new materials properties intended to increase dynamie resistance and integrity of structures. The key experimental results are presented which represent the achievements obtained on national and international levels in Bratislava, Iasi, Skopje, Seriate and Ispra. Related analytical studies done so far in Bucharest, Opole, Skopje and Bratislava created the basis for more smart calculations approach when the design resistance is being to assess. Displacement - force dependence through seismic response spectra were applied for simple masonry structure and R/C frame with reinforced masonry infills. The procedure follows in details the stress-deflection stage when higher dynamic seismic or other actions appear. The recoramended behaviour limits are analysed in relation to the ductility and resistance capacity of the respective structural system. The applied option suggests the verification of expected ultimate stresses and deformation. Thus, the performance analysis gives the indices whether the structure is provided with sufficient dynamie resistance capacily against the damage.
