Analisis Struktur Green Concrete Gedung Bertingkat 2 Lantai di Bandara Berbasis Aplikasi SAP 2000 V22

Abstract

Waste is the residue of daily human activities. Waste tends to be able to cause ecological crises and trigger the development of diseases in humans. Therefore, waste needs to be recycled, especially inorganic waste. The current waste recycling process can be used as an aggregate replacement building material, and several tests have been carried out is green concrete. Experimentally, green concrete has been tested with results when replacing 5% fine aggregate has a percentage of concrete strength of 97.4% against normal concrete. Green concrete needs to be structurally analyzed before being tested in manufacturing simple-level buildings. The analysis process is carried out with the SAP 2000 V22 application as a simulator of structural behavior based on parameters related to green concrete. This analysis aims to evaluate the accuracy of reliability, and performance of the building structure. This study uses the LRFD (Load and Resistance Factor Design) method to determine the load received by the structure by considering the resistance factor of the material used. The results of this study show that the three simulations of concrete data with compressive strengths of 17 Mpa, 19 Mpa, and 20 Mpa have no structural irregularities and are safe to use. However, using 19 Mpa and 20 Mpa structural concrete is still recommended. This is because the mechanical characteristics of concrete are not only determined by compressive strength, but there are other factors, such as flexural strength, shear strength, modulus of elasticity, and other physical properties.
