Abstract

Failures due to shear are brittle and required reliable strength models. The challenge of refining those methods has been brought to question recently. This research study aims at applying recent reliability approaches for the case lightweight concrete (LW) slabs under shear. The American Concrete Institute (ACI) was selected. An experimental data base gathered from existing literature was implemented. A brief review of both the Second-Order Methods (SORM) and First-Order Method (FORM), which are commonly used for the computation of reliability are outlined. The FORM was selected to calculate the sensitivity index and reliability index were calculated for the ACI. A comparative analysis between those indices and the internationally set target ones was conducted. The ACI was found to be lacking the adequate reliability. Thus, ACI provision was optimized to achieve target reliability indices.
