Displacement capacity of masonry buildings as a basis for the assessment of behavior factor : an experimental studyTomaževič, Miha ; Weiss, PolonaThe results of shaking table tests of a series of 1:5 scale masonry building models have been used for the assessment of values of structural behavior factor q for masonry structures, seismic force ... reduction factors proposed for the calculation of design seismic loads by Eurocode 8, European standard for the design of structures for earthquake resistance. Six models have been tested, representing prototype buildings of two different structural configurations and built with two different types of masonry materials. The study indicated that the reduction of seismic forces for the design depends not only on the type of masonry construction system, but also on structural configuration and mechanical characteristics of masonry materials. It has beenalso shown that besides displacement and energy dissipation capacity, damage limitation requirement should be taken into account when evaluating thevalues of behavior factor. On the basis of analysis of experimental resultsa conclusion can be made, that the values at the upper limit of the proposed range of values of structural behavior factor q for unreinforced and confined masonry construction systems are adequate, if pushover methods are used and the calculated global ductility of the structure is compared with thedisplacement demand. In the case where elastic analysis methods are used and significant overstrength is expected, the proposed values are conservative. However, additional research and parametric studies are needed to propose the modifications.Vir: Bulletin of earthquake engineering. - ISSN 1570-761X (Vol. 8, iss. 6, Dec. 2010, str. 1267-1294)Vrsta gradiva - članek, sestavni del ; neleposlovje za odrasleLeto - 2010Jezik - angleškiCOBISS.SI-ID - 1667431
