Abstract

This study is aimed to explore how to simply predict the failure of glass reinforced concrete. A lack of design by analysis using FEM has a plenty extensive technique, particularly for reinforced concrete structure cases. Their ingredient are complicated hence induce time costly analysis caused by DOF booming due to an severe computation concerned size of grains, reinforcement, pull out bonds, meso-scale properties and initial cracks, cover spalling and delaminations. Some real concrete based softwares were costly and hard to be run because their complexity input needed. An eco-friendly beam structure using glass strips waste as reinforcement called GLARC (Glass Reinforced Concrete) has been proposed and need to be simply analysis, something convenient but quiet proper for design aims, hence the failure behavior should be easy to predict and its criterion should be known well. Contrast to the deformations and strains that have a strong affiliation with material model, the stresses are fairly free from material model because actually they are loads. Hence standard linear FEM software adequate enough to use as initial analysis GLARC system or its design aims. In this study, a GLARC beam was used as typical example and 4 points bending loads was applied. Initially, the failure will be occurs first at the tensioned part of the concrete and then the next failure sequences were concrete cracks, then glass strip breaks or slip to concrete, before its failure. The maximum deflection around loading zone was 0.815 mm, this show that another nonlinear responses have not been taken into account. This simplified analysis will be a proper-useful way to design a GLARC structural system.
