Abstract: The complicated mechanical behaviour of joints and connections in precast constructions creates a significant amount of uncertainty. This study explores the dependability of precast joint bonding stress as a function of grout compressive strength, height and thickness of wall panels. The first crack load and vertical displacement data were acquired experimentally for this work. The reliability analysis of precast joints in wall assemblages is estimated in two different ways: estimating the central safety factor using Monte Carlo simulation and analysing survival probability using the Weibull distribution model. The novelty of the work is to relate Weibull survival probability estimates to predict first crack load and to propose the usage of the Weibull model as a novel designer's tool for cost-effective optimum design of precast joints.

Keywords: precast walls; reliability analysis; Weibull distribution; failure rate analysis; reliability index; probability of failure.
