S45C carbon steel is a common engineering steel and widely used for many industrial applications such as machine structures, gears, shafts, axles, bolts, etc. The purpose of this research is to investigate the cutting parameters (feed rate and spindle speed) in different levels to evaluate the surface roughness (Ra) of S45C steel in the dry…
In this study, two-way reinforced concrete (RC) slabs were studied and evaluated using different methods including Moment Coefficient Method (CM), Direct Design Method (DDM) and Equivalent Frame Method (EFM). Moreover, the design of RC slabs was also conducted by computer program, ETABS 2021. The slab chosen to study was the 6m x 6m two-way slab…
To find ways of reducing the risks of lateral torsional buckling on the perforated sections in web by adding transverse stiffeners is the purpose of this study. The comparison of the T-shaped transverse stiffeners and normal transverse stiffeners was found that the use of T-shaped transverse stiffeners with the thickness increasing, reduce the lateral displacement…
Fiber Reinforced Polymers (FRP) has known as the most essential materials for structure strengthening. Most of old and new structures were selected FRP for strengthening in Cambodia and other countries. The aim of this study is to explore more detail about the methods and techniques involved in strengthening structure by using FRP. FRP is really…
To avoid collapse under wind load and seismic forces in tall building shear walls are provided. Shear wall arrangement must be absolutely accurate, because if not, it will cause negative effect instead. When the mass center and hardness center coincide with each other, the distance of shear wall from the mass center also plays an…
This study focused on the shear strength and flexural strength of enlarged-section reinforced concrete beams strengthened with FRP after the repaired section. Four cross-sections are proposed to calculate the shear strength and flexural strength in accordance with the building code, ACI 440.2R. In addition, 33 sample beams were calculated in accordance with three building codes…
Reinforced concrete (RC) jacketing of RC columns is used to increase the load-carrying capacity of RC columns with insufficient strength. The method of RC jacketing is an easy and cost-effective method. The confinement action is influenced by the stirrups in concrete core, stirrups in RC concrete jacketing, the thickness of RC jacketing, and the strength…
Ultra-high performance concrete (UHPC) is suitable for the durable rehabilitation and strengthening of deteriorated normal strength concrete (NSC) structures due to its excellent characteristics, such as superior compressive strength, high tensile capacity, and excellent bond properties. However, a successful repair depends on whether the UHPC-NSC interface can provide good bonding performance under various applied loads…
The world nowadays is plagued by COVID-19, a global infectious disease. The COVID-19 infection causes many problems in human life. Most of the buildings are not suitable for inflection diseases due to a lack of design, hygiene, comfort, and resistance to infectious diseases. The disease is closely related to air, so we can solve architectural…
The purpose of this paper was created a process by means of which to develop an application for calculation and numerical simulation of the 2-dimensional of furnace glass of heat transfer as heat conduction and heat convection. All of this, applying to experimental was cased reality-based where numerical simulation has been chosen, which was the…
