The Influence of structural irregularities on response of the RC buildings subjected to mining tremors and earthquakes

Abstract

The seismic design of structures seems to be a completely recognized subject. There are requirements and guidelines that must be looked at by

planners in seismic zones. The problems occur while irregular structures are concerned especially while structures are subjected to dynamic earthquake-like excitements. An example of such vibrations is mining tremors. In Poland, the problem of seismic behavior of irregular buildings subjected to mining-induced seismicity is still an unsolved problem. In this paper numerical studies are carried out for five-storey building models with six various types of irregulars in plan. In this article, the response of the studied models was compared by linear dynamic analysis (Response Spectrum). The difference between the response of the structure to earthquakes and mining tremors is presented. Lately, several numerical simulations have been done to research the building behavior under mining tremors and earthquake shaking. There is still a necessity to research and compare the results of numerical analyses prepared for the same subject and the same soil cases. The aim of this paper is to present the differences between mining tremors and earthquakes.
