Indonesia is located in a region with high seismic activity; therefore, earthquake-resistant structures are strongly recommended. This study evaluates the behavior of prestressed hollow columns made of geopolymer concrete under combined cyclic and axial loading through finite element method simulations using ANSYS software. The study utilizes secondary data in the form of geopolymer concrete ma…
Flat slab is a two-way concrete slab without beams that accelerates construction and reduces structural depth, but it is prone to brittle failure at the slab–column connection. This study aims to analyze the punching shear capacity of geopolymer concrete flat slabs with variations in drop panel thickness under monotonic loading. The analysis was carried out using ANSYS based on the finite ele…
One of the structural elements designed to withstand earthquakes is the beam-column joints. The joint zone is an area that is responsive to earthquake load distribution, so the right design must qualify seismic criteria. The difficulty of compacting conventional concrete due to the density of reinforcement can be overcome by self-compacting concrete material. This research purpose to analyze th…
Dinding merupakan salah satu elemen non struktural dalam sebuah konstruksi gedung. Dinding konvensional umumnya menggunakan material bata merah, tetapi perkembangan jaman telah menciptakan material dinding yaitu panel dinding. Pada penelitian ini akan menganalisis pengaruh beban siklik terhadap elemen dinding dengan ukuran 1500 mm x 1500 mm dengan ketebalan 200 mm, dengan variasi berupa bukaan …
Geopolymer mortar is an alternative to conventional mortar where the basic material does not use portland cement as a binder but uses fly ash which is activated with an alkaline solution. The purpose of this study was to determine the effect of NaOH concentration on the characteristics of geopolymer mortar. The research method is an experimental method using various concentrations of alkaline a…
