Abstract

Axial, flexure, and shear loads are the most common loads that could impact any structure. For instance, wall panels and columns majorly carry axial loads from the beam and slabs; they are also susceptible to flexure and shear loads from the wind or earthquake loads. Insulated concrete form (ICF) is a portable component of interconnected expanded polystyrene (EPS) panels filled with concrete. EPS remains in place and becomes part of the wall to enhance thermal resistance and structural performance. This paper focuses on an experiment that investigated the performance of ICF wall panels under axial compression and flexure. EPS with a higher density of 20 and 40 kg/m3 and a higher thickness of 50 and 100 mm was selected to prepare ICF wall panels for this experimental investigation. In addition, the plain concrete panel was cast for reference. Axial, flexure, and shear load-carrying capacity, load displacement, load–deflection profiles, crack propagation patterns, failure nature, and strain energy are analyzed and reported in this paper. It was observed that ICF panels were superior to plain concrete panels in terms of axial, flexure, and shear load-carrying capacity, failure nature, and absorbed strain energy.

探索在轴向压缩和弯曲条件下,发泡聚苯乙烯(EPS)对保温混凝土模板(ICF)墙板的影响
轴向荷载、挠曲荷载和剪切荷载是可能对任何结构产生影响的最常见荷载。例如,墙板和柱子主要承受来自梁和板的轴向荷载;它们还容易受到来自风荷载或地震荷载的挠曲荷载和剪切荷载的影响。保温混凝土模板(ICF)是一种由相互连接的发泡聚苯乙烯(EPS)板组成的便携式组件,其中填充有混凝土。EPS 可保持原位,成为墙体的一部分,以增强热阻和结构性能。本文重点介绍了一项研究 ICF 墙板在轴向压缩和弯曲情况下性能的实验。本次实验研究选择了密度分别为 20 和 40 公斤/立方米、厚度分别为 50 和 100 毫米的高密度发泡聚苯乙烯来制备 ICF 墙板。此外,还浇注了素混凝土面板作为参考。本文分析并报告了轴向、弯曲和剪切承载能力、荷载位移、荷载-挠度曲线、裂缝扩展模式、破坏性质和应变能。结果表明,ICF 面板在轴向、弯曲和剪切承载能力、破坏性质以及吸收的应变能方面均优于素混凝土面板。
