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 case study presents the analysis of basic wind speed and serviceability evaluation of tall rein-forced concrete buildings under wind and earthquake in Phnom Penh. The objectives are to examine the basic wind speed in Phnom Penh and to compare the serviceability with earthquakes. First, the wind data collection from Phnom Penh Airport was analyzed…
This paper deals the research allowed to estimate influence with organize cracked in reinforced concrete beams on their stiffness and crack resistance under long-term loading.
The experimental and theoretical research of the single-span reinforced concrete beam with artificial flaw in tension area under the action of static short-term loads is performed. The stress-strain state of the structure, based on numerical simulation using finite element software system ANSYS, is investigated. The results of numerical simulation are compared with the experimental results.…
Discrepancies in the current design guidelines on externally bonded FRP shear strengthening for reinforced concrete (RC) structures had initiated this research study. It is generally believed that the erroneous and irrelevant effective FRP strain models adopted in many of the design guidelines, which are derived entirely based on the 45-deg truss analogy, contributes significantly for…
Reinforced concrete (RC) structural members strengthened with ultrahigh-performance concrete (UHPC) have shown excellent performance in past experimental investigations. However, methods of predicting their capacity are currently very limited. This paper presents six independent methods of predicting the shear capacity of UHPC–concrete composite members based on the application of existing design codes. Three of these methods…
