Design of Hybrid High-Performance Concrete (HPC) and Lightweight Aggregate Concrete (LWAC) Sandwich Panels

摘要

The paper outlines an optimum (minimum cost) design procedure for hybrid precast structural sandwich panels made of high-performance concrete faces and a lightweight aggregate concrete core. The strength-based design approach deals with flexure, vertical shear and horizontal shear (debonding) due to out-of-plane monotonic loading within the format of Eurocode 2. Of the failure modes analyzed debonding receives special attention and preliminary experimental results on facecore bond constitutive laws are presented.
