Experimental measurement-based FE model updating and seismic response of Santa Maria Church and its guesthouse building

Abstract

This paper offers a structural assessment of the historical Santa Maria Church and its Guesthouse building in Trabzon, Turkey. This process involves non-destructive experimental investigation using ambient vibration test and numerical evaluation using finite element method. Finite element model updating procedure was employed for the buildings using experimental data such as dynamic features provided by the ambient vibration test. Time-history analyses were carried out by using initial and final finite element models to draw attention to the effectiveness of the finite element model updating procedure and evaluate the seismic performance. The 1992 Erzincan earthquake ground motion data was used for seismic analysis. The ground motion was exposed to buildings in bidirectional. The maximum displacements and principal stresses are detailed at the end of the analysis using contour diagrams. Result of the analyses, the buildings demonstrated a Limited Damage Performance Level throughout the imposed seismic record according to the Earthquake Risk Management Guide for Historical Structures which is a formal guide.
