A Numerical Analysis of The Modulus of Elasticity of The Graded Concrete

Abstract : Graded concrete is one of the functionally graded materials in civil engineering that can reduce the use of cement to create a high-performance structural element. The graded concrete

FINITE ELEMENT ANALYSIS OF T-SECTION RC BEAMS STRENGTHENED BY WIRE ROPE IN THE NEGATIVE MOMENT REGION WITH AN ADDITION OF STEEL REBAR AT THE COMPRESSION BLOCK

Abstract : A building whose functions are converted in which their volumes are improved, for example, a four-story building transformed into a five-story building, resulting in a dead load improvement

Seismic Vulnerability Assessment Using Rapid Visual Screening: Case Study of Educational Facility Buildings of Jenderal Soedirman University, Indonesia

Abstract : Earthquakes are natural phenomena occurring in various parts of the globe. Severe earthquakes caused substantial loss of life and property when nearly populated districts. Although some progress has

On the Performance of a Multi Story Irregular Apartment Building Model Under Seismic Load in Indonesian Moderately High Seismicity Region

Abstract : Purbalingga is regency with a potential moderately high seismicity requiring compliance of planning and implementation rules of the earthquake-resistant structural system. The purpose of this research is to

Two nodes cusp geometry beam element by using condensed IGA

Abstract : A cusp is a curve which is made by projecting a smooth curve in the 3D Euclidean space on a plane. Such a projection results in a curve

Compressive Strength Analysis On Geopolymer Paving By Using Waste Substitution Of Carbide Waste And Fly Ash

Abstract : The method to make paving sample in this research was done by mixing fly ash, carbide waste, sand, and alkali activator in the form of sodium silicate (Na2SiO3),
