Abstract

This study aims to obtain the average compressive strength of cylindrical column concrete specimens reinforced with an e-glass fiber laminate composite wrap based on variations in the number of wraps. In addition, in this study, the compressive strength and damage patterns will be analyzed to obtain the performance of the sheath in the concrete structure. The test specimens were molded according to the ASTM C39 standard with a diameter of 50 mm and a length of 150 mm. The process of applying laminated composite wrap to concrete specimens is carried out using the vacuum bagging method. The compressive strength test on the specimen is carried out by providing an axial load on the specimen until it failures. The results obtained are that the compressive strength of the specimen has increased significantly due to the provision of e-glass fiber wrap. A significant increase in the compressive strength of concrete specimens occurred in 3 layers of e-glass fiber wrap which reached more than 60%. Furthermore, the ability of the e-glass fiber wrap in protecting the cylindrical concrete structure due to the applied load also experienced an increase in performance in the 2 and 3 layers of the e-glass fiber wrap.

Abstract

Three-dimensional (3D) imaging technology for computer-assisted construction planning of a product through a simulation process is now having a very positive impact in helping to improve the construction results of a product. The honeycomb shape has better strength in accepting constant and stable loads and has a lighter structure. Aluminum honeycomb using the sandwich construction method was analyzed by simulation using Ansys software in this research based on 3 variations in hexagonal cell geometry due to differences in the applied static load. The influence of the hexagonal honeycomb cell geometry shows a contribution to the deformation capability of the material at varying load angles, namely an increase of 100% at a load angle of 60° and a higher spike of around 130% for a load angle of 90°. Variations in the hexagonal honeycomb geometry still have an impact on increasing material capability. of 128% in the 6 mm hexagonal cell model with a load angle of 90°. The geometric intensity of the honeycomb hexagonal cell produces expansion values respectively in material deformation and equivalent stress based on the load angle of 15% and 35%.
