Recycle Aggregate Concrete (RAC) is a common “green” product used for a variety of purposes, although the durability and strength of the material still need more research to adequately determine influences on these parameters. The failure pattern, punching bearing capacity, and deflection variation of wallboard of both ordinary concrete and RAC with various rebar reinforcement diameters and spa...

Contrary to top-loaded deep beams, Inverted-T (IT) beams are loaded on ledges at the beam’s bottom chord. The presence of load near creates a tension field in web loading points. An experimental investigation was carried out which 8 specimens reinforced concrete IT were tested and effect following variables studied: changing hanger diameter, arrangement terms spacing distribution distance, rein...

ABSTRACT The issue of environmental protection has led researchers to pay serious attention to waste tires. Civil engineers have found that waste tires can increase bearing capacity, earth slope stability, and other useful applications in civil engineering. In this paper, a series of experimental modeling have been performed to investigate the effect of waste tires on increasing the stabi...

Shear failure of B-C joints is recognized as the primary cause collapse various moment-resisting frame buildings during recent earthquakes. When joint subjected to huge forces severe ground shaking and its behaviour has a very much influencing on structure, sometimes it may Leeds entire structure. To study energy dissipation with different types combinations FRP sheets used retrofit BC in this ...

Rebar fracture in boundary elements of lightly reinforced shear walls in recent earthquake motivated research on the minimum longitudinal reinforcement applicable to shear walls. These researches lead to change in the ACI 318-19 requirement for minimum longitudinal reinforcement in boundary elements. New ACI 318 requirement increase minimum longitudinal reinforcement ratio for boundary elements...

Reinforced concrete (RC) structures may be subjected to an increase in load, severe environmental attack, and other factors that lead deterioration. Strengthening/repair techniques are typically used upgrade the strength or enhance durability, which extends service life of structures. In current study, behavior reinforced beam strengthening by UHPC layer with/without construction joints were in...

faced with the challenges of healthcare reform, skills and new capabilities are needed to support the reform and it is of crucial importance in africa where shortages affects the health system resilience. edwards et al provides a good example of the challenge of implementing a mentoring program in one province in a sub-saharan country. from this example, various aspects of strengthening the cap...
