On-Site Experimental and Numerical Investigations of Latticed Girder Composite Slabs

In this study, on-site bending experiments which represented realistic and pragmatic engineering applications were performed to investigate the resistance, deflection, cracking process of latticed girder composite slabs. Then, utilizing ABAQUS software, nonlinear finite element (FE) models established behavior The modeling took into account contact between precast cast-in-place concrete interfaces. Additionally, a damage-cracking methodology was introduced evaluate crack opening width slab. results demonstrated that proposed numerical model capable reproducing typical slabs’ performance analysis. experimental demonstrate lattice slabs conformed requirement existing design codes.
