Sažetak
This paper presents the experimental tests of 1/3 scaled, one storey, one bay masonry- infilled steel frames on a shake-table. Two types of infilled frames were considered: one with central door opening and another without opening. Each type was tested in variants of unreinforced plaster and plaster reinforced with a PVC mesh. Masonry elements made of autoclaved lightweight concrete were used. The tested specimens were exposed to the series of artificial accelerograms with gradually increasing amplitude. The artificial accelerograms were chosen to match the elastic response spectra. Characteristic displacements, accelerations and strains, as well as structural deformations and crack patterns in the masonry were observed during the test. Test results show the efficiency of the PVC mesh in a plaster by reducing the crack zones in it. Also, the specimens without opening exhibited a better performance than those with the central door opening. Afterwards, a developed numerical model for nonlinear dynamic analysis of planar structures composed of concrete, steel, masonry and plaster was used to simulate the performed tests. Fairly good agreement is observed between experimentally determined and numerically obtained results.
