本文介绍了预制泡沫混凝土夹芯板（PFCSPs）的实验和分析研究结果。进行了6个PFCSP的足尺试验，研究了轴向载荷下面板的性能。采用泡沫混凝土（FC）浇注PFCSP混凝土网壳。记录和讨论了轴向承载能力、载荷-挠度曲线、载荷-应变关系、长径比、载荷-位移、载荷-变形、破坏和倒塌模式、开裂模式和轴向载荷恒定增量下的扩展。简要介绍了FC的性质和用途。将试验结果和有限元分析结果与基于美国混凝土协会（ACI）实心混凝土墙设计公式的理论计算值以及前人提出的可用于预测夹芯板极限承载力的经验公式进行了比较。根据室内试验和有限元分析结果，提出了半经验公式。(c)2016爱思唯尔有限公司版权所有
This paper presents results from an experimental and analytical study of precast foamed concrete sandwich panels (PFCSPs). Full-scale experimental tests of six PFCSPs were conducted to study the behavior of the panels under axial loads. Foamed concrete (FC) was used to cast PFCSP concrete wythes. The axial load-bearing capacity, load-deflection profiles, load-strain relationships, slenderness ratio, load-displacement, load-deformation, failure and collapse modes, cracking patterns, and propagations under constant increments of axial loads were recorded and discussed. The properties and use of FC were briefly reviewed. Results of the experimental test and finite element analysis were compared with the theoretical values calculated based on the American Concrete Institute (ACI) design equation for a solid concrete wall and other empirical formulas developed by antecedent researchers which might be applicable to predict the ultimate load-bearing capacity of sandwich panels. A semi-empirical formula was proposed based on the laboratory test and finite element analysis results. (c) 2016 Elsevier Ltd. All rights reserved.
