Abstract

The new generation of lightweight, prefabricated structures are recently becoming more popular in European market. The new trends are bringing multistory timber structures and business buildings. Special attention is paid to buildings located in earthquake prone areas of middle and south Europe. Therefore, the appropriate structural upgrade should be implemented in existing structural systems to increase their seismic resistance. Slovenian companies are well established in North-European market where earthquake is not the major issue in structural design. The new European directives and standards (Construction Product Directive, Eurocodes) is more demanding regarding to seismic resistance of structures in Middle Europe (Italy, Slovenia) and South Europe (Greece, Portugal, Turkey). Therefore, our industry of prefabricated timber structures should follow the demands if it would like to be present in these particular segments of European market. Within the proposed project, the basic timber wall panels produced by company RIKO HIŠE d.o.o., will be tested by combined constant vertical and cyclic horizontal load. In addition, comparative tests with monotonous horizontal load according to SIST EN 594 will be carried out. The influence of anchoring systems to shear stiffness and strength of timber wall panels will be evaluated. The existing anchoring system of wall panels will be upgraded according to the findings of test results. The main data obtained from test results will be: initial stiffness, load carrying capacity, ductility, stiffness degradation at reversed cycles of loading, energy dissipation and failure mechanisms and modes. The experimentally obtained knowledge about tested type of structural elements will enable further development of numerical models of mechanical joints and wall panels. The upgraded model will be used for simulation and prediction of behaviour of structural elements and building structure as whole when exposed to earthquake excitation.
