The objective of this study is to determine seismic behaviour of masonry buildings with reinforced plaster mortar, with a particular focus on the modification of structural response due to application of the polypropylene and steel reinforced plaster, as compared to an ordinary type of plaster. The resistance of one-storey single-span masonry buildings subjected to seismic load on the shaking table is investigated in the study. Experimental results revealed natural periods, response acceleration spectrums, and spectrum interactions of masonry buildings. In addition, finite element models of test buildings were established, and their results were compared with those obtained during experimental study.

The application of weight losses to investigate corrosion effects on structural behaviour of an offshore structure under wave loads is presented in this study Weight losses of sections obtained during previous experimental studies are implemented in the model. The jacket type structural model is analysed in its intact and deteriorated forms to demonstrate corrosion effects. The ABAQUS finite elements program is utilized and the fluid structure interaction (FSI) technique is adopted when modelling the interaction between solid and fluid domains. Mode shapes, first three natural frequencies, displacements of selected points, and maximum stresses, are comparatively presented.


Changes in natural frequencies, modal shapes, and damping ratios of a two story single span reinforced concrete building having different stirrup spacing in columns are analysed in the paper. Two building models measuring 150 × 150 × 135 cm were manufactured for the testing. Dynamic properties of both buildings were experimentally determined using the operational modal analysis. The ABAQUS finite element software was used to numerically determine dynamic properties of the buildings. The effect of stirrup densification in columns on dynamic properties of the building was defined by comparing experimental and numerical analysis results.

The determination of behaviour of structural members under load has become increasingly prominent with current advances in technology. The effect of impact on solids should not be ignored. The impact behaviour of non-reinforced concrete beams is investigated in this study both experimentally and using the finite element analysis. Members are tested in laboratory, and the ABAQUS software is used in the analysis. Accelerations, velocities, displacements, impact forces, and energy absorption capacities, have been obtained in the scope of these analyses.


Steel lattice masts rank among the most efficient load-bearing structures in the field of high-rise construction. The non-linear analysis of a guyed steel lattice mast is conducted using the SAP 2000 finite-element program for different ice thickness values at 1500 m of altitude. After definition of the geometrical model and cross-section properties, various load combinations are analysed. Finally, the wind speed - ice thickness relationship is obtained, and the maximum wind speed that the structure can withstand is determined for varying ice thicknesses. © 2015, Union of Croatian Civil Engineers and Technicians.
