reinforced concrete

The main objective of this study is the development of a simple and reliable method for identifying structural vulnerability of low-rise reinforced concrete buildings. The desired attribute of the method is that it enable quick evaluation by construction professionals without ex…

Findings from previous studies have indicated that a reinforced concrete wall with a structural hinge at the base, used to reduce the strength requirement for the foundation, can be effective for limiting the drift demand for frames subjected to strong ground motions. The goal o…

This dissertation investigated progressive collapse analysis of three-dimensional (3D) reinforced concrete (RC) frames that are optimized for carrying structural loads by introducing a unique simultaneous multi-column removal load path. While the concept of removing a key struct…

Although the interstory drift ratio is used as a limiting factor for specific performance levels by the structural engineering profession, its distribution among the stories is generally disregarded. Observations and analytical studies have shown that even the structures are des…

The reinforcement detailing of reinforced concrete frame and wall-frame structures, in regions where the probability of a seismic event is not significant, is characterized by lack of special consideration for meeting ductile response requirements. The buildings are normally des…

The feasibility of detecting and quantifying delamination at the interface between steel (or GFRP) bar and concrete using ultrasonic guided waves is investigated in this study. These waves can propagate a long distance along the reinforcing steel (or GFRP) bar or concrete beam a…

Performance-Based Design (PBD) has gained popularity as a procedure for the seismic design of structures. In order to achieve the objectives of PBD, it is essential to have accurate modelling approaches. Non-linear Time History Analysis (NLTHA) is the most complex technique that…

There are a large number of reinforced concrete (RC) buildings in seismically active areas of the world that are not designed and constructed in accordance with modern seismic design provisions. These buildings are vulnerable to severe damage or collapse due to their low lateral…

Reinforced concrete is an important material in the building industry but its durability is limited mainly due to corrosion of the steel reinforcement. In almost all cases, degradation of concrete is ultimately related to the presence of water and the transport of dissolved ions…

Durability of reinforced concrete structures in Arabian Gulf region is a major problem which results from corrosion of the reinforcement occurring as a consequence of chloride transport in concrete. Although chloride-induced corrosion is directly influenced by the chloride diffu…

Structural health monitoring (SHM) is a research field that targets detecting and locating damage in structures. The main objective of SHM is to detect damage at its onset and inform authorities about the type, nature and location of the damage in the structure. Successful SHM r…

The interaction in earthquakes of reinforced concrete frames with infill masonry walls has long been a subject of strong interest because of their abundance in regions of high seismic risk. A model was created to provide a simple method to analyze the behavior of reinforced conc…

The objective of this study was to investigate the Corner-Supported Element (CSE) of Hillerborg's Advanced Strip Method (ASM). The investigation includes the five basic cases of the CSE. The aims of the investigation were, first, to improve the CSE's behaviour; and, second, to e…
