Analytical Investigation of the Influence of Seismicity on the Construction Cost of the R/C Load-Bearing Structure of a 5-Storey Building With Spring Supports

Abstract

Greece is divided into three seismic hazard zones ZI, ZII, ZIII. In the present research work, the same building in the three seismic zones of Greece is modeled, analysed and dimensioned and then the construction cost of its structural body is estimated. The building modeling was performed in SAP2000 using linear finite elements. The analysis of the building was performed by dynamic spectral analysis methods using the design spectrum of EC8. A 5-storey building with a standard floor plan per floor was used. The supports in this building were simulated using springs to take into account the influence of the soil. The purpose of this research paper is through comparative analytical estimation of construction costs to demonstrate whether the cost of construction of the bearing structure of a reinforced concrete building is affected by the area seismic hazard, if this influence is significant and to what extent. Useful conclusions are drawn regarding the influence of seismicity on the construction cost of the load-bearing structure of reinforced concrete buildings with spring supports.
