Modelling and Seismic Response Analysis of Non-residential Single-storey Existing Precast Buildings in Italy

Abstract

Old precast buildings are often characterized by poor detailing that may hamper the structural performance particularly in the case of earthquakes. This is essentially related to: (i) a limited past knowledge of seismic design and behaviour, also reflected in past building codes; (ii) the evolution of seismic zonation of the Italian territory. The aim of this work is assessing the probabilistic seismic vulnerability with respect to the usability preventing damage and global collapse performance levels of four existing single-story precast buildings designed in accordance with past Italian building codes from 1960s to 1990s in three sites with increasing seismic hazard.

Comparing the Observed and Numerically Simulated Seismic Damage: A Unified Procedure for Unreinforced Masonry and Reinforced Concrete Buildings

“…Given the purposes of this study, the nonlinear model of the case-study structure was built in OpenSees software (McKenna et al 2000) according to the assumptions and approaches adopted for the assessment of the archetype buildings analyzed for RINTC-e project. These assumptions and approaches are briefly recalled in this section, but more details are reported in De Risi et al (2022) and in Di Domenico et al (2022) for RC buildings and in Bosio et al (2021) for PRC buildings. A sketch of the modelled structures (the RC case is represented without infill walls for the sake of clarity) is reported in Figure 16.…”

Simulation on seismic performance of the post‐fire precast concrete column with grouted sleeve connections

“…[1][2][3][4][5] It was found that numerical simulation model fulfilled the reinforced concrete frame building's dynamic respond performance after an earthquake attack, 1 and connections was one of the vulnerable factors for the precast buildings in the seismic regions. 2 In addition, the dowel connections were characterized by an overstrength and was proposed to update the relevant Italian design guidelines. 3 Through introducing a forcebased finite element method, it was found that the numerical method was feasible to predict the mechanical behaviors, including bearing capacity, failure modes and distribution of internal forces, of frame and wall structures correctly.…”

“…A large number of researches have been exerted to investigate the mechanical performances of frame and shear wall structures 1–5 . It was found that numerical simulation model fulfilled the reinforced concrete frame building's dynamic respond performance after an earthquake attack, 1 and connections was one of the vulnerable factors for the precast buildings in the seismic regions 2 . In addition, the dowel connections were characterized by an overstrength and was proposed to update the relevant Italian design guidelines 3 .…”

“…Nowadays the precast concrete structures mainly include the frame structure and the shear wall structure. A large number of researches have been exerted to investigate the mechanical performances of frame and shear wall structures 1–5 . It was found that numerical simulation model fulfilled the reinforced concrete frame building's dynamic respond performance after an earthquake attack, 1 and connections was one of the vulnerable factors for the precast buildings in the seismic regions 2 .…”

Seismic Risk and Finite Element Modelling Influence of an Existing One-Storey Precast Industrial Building

“…The results described in this article has been partly obtained during an Italian national project (i.e., RINTC-E, Iervolino et al 2022;Bosio et al 2022) aiming at assessing the seismic risk of existing structural typologies as a function of past building codes prescriptions. The focus of this paper is placed specifically on one of the precast buildings addressed in the project by additionally addressing the influence of the modelling strategies of typical seismic vulnerabilities and including the assessment of direct losses and required retrofit time.…”
