The paper presents an extensive assessment of seismic performance of code-conforming single-story precast buildings, with focus on seismic reliability. Single-story RC precast buildings designed according to Italian building code are considered as case studies, varying site seismicity, building geometry layout, and soil type. Nonlinear time history analyses are performed considering three-dimensional models and bi-directional seismic excitation. Several damage criteria and damage states (DSs) were considered for the assessment of the reliability indexes, according to damage limitation, life safety, and near collapse performance levels (PLs). The paper contributes to the literature in terms of (a) technical guidance for expeditious assessment of reliability of precast buildings, (b) quantitative findings associated with reliability of code-conforming Italian precast buildings, and (c) recommendations towards a more reliable design/assessment of precast buildings.

Abstract

The paper presents an extensive assessment of seismic performance of code-conforming single-story precast buildings, with focus on seismic reliability. Single-story RC precast buildings designed according to Italian building code are considered as case studies, varying site seismicity, building geometry layout, and soil type. Nonlinear time history analyses are performed considering three-dimensional models and bi-directional seismic excitation. Several damage criteria and damage states (DSs) were considered for the assessment of the reliability indexes, according to damage limitation, life safety, and near collapse performance levels (PLs). The paper contributes to the literature in terms of (a) technical guidance for expeditious assessment of reliability of precast buildings, (b) quantitative findings associated with reliability of code-conforming Italian precast buildings, and (c) recommendations towards a more reliable design/assessment of precast buildings.
