Abstract:
Post-earthquake reconnaissance and results of previously conducted experiments show that stiffness and strength deterioration of beam-column joints can have a detrimental effect on the integrity and vulnerability of reinforced concrete frame structures, especially in older buildings in developing countries. As a result, there is a need to develop efficient structural evaluation techniques that are capable of accurately estimating the strength and deformability of existing buildings to facilitate the development of safer, simpler, and lower cost retrofit solutions and thus contributing to risk

Abstract:
This research investigated the behavior of nonseismically detailed reinforced concrete exterior beam-column joints subjected to bidirectional lateral cyclic loading using nonlinear finite element analysis (NLFEA). Beam-column joints constitute a critical component in the load path of reinforced concrete buildings due to their fundamental role in integrating the overall structural system. Earthquake reconnaissance reports reveal that failure of joints has contributed to partial or complete collapse of reinforced concrete buildings designed without consideration for large lateral loads, resulti

Abstract:
Most of the experimental studies available in literature on the seismic assessment and retrofit of existing, poorly detailed, reinforced concrete (RC) beam-column joints typical of pre-1970s construction practice have concentrated on the two-dimensional (2D) response, using unidirectional cyclic loading testing protocols and a constant column axial load. Even more limited information is available on the performance of corner three-dimensional (3D) RC beam-column joints with substandard detailing subjected to a bidirectional-loading regime. In addition, little effort has been dedicated to the d

Abstract:
The vulnerability of exterior beam-column joints in existing RC buildings represents a key aspect to ensure structural integrity of buildings under seismic loadings. Recent seismic aftermaths showed substantial damages resulting from beam-column joints in older-type non-seismically designed frame structures, often leading to undesirable brittle failure mechanisms. RC buildings constructed prior to developing current seismic codes and guidelines generally lack joint transverse reinforcements. As a result, the seismic assessment of existing RC buildings necessarily requires to consider beam-col

Abstract:
Prior studies indicated that beam-to-column connections of reinforced concrete (RC) moment resisting frame structures experience considerable deformations under earthquake loading and these deformations have a major contribution to story drift of the building. In current analysis and design applications, however, the connection regions are generally modeled as rigid zones and the inelastic behavior of the joint is not taken into account. This assumption gives rise to an underestimation of the story drifts and hence to an improper assessment of the seismic performance of the structure. In order

Each parameter was varied by a power function, while the linear correlation coefficient between each parameter and performance indicator was recorded.

Abstract:
Old reinforced concrete buildings are vulnerable to seismic actions as they were built in accordance with non-seismic code provisions and suffer from poor material quality and/or reinforcement detailing. Moreover, many buildings were constructed without even basic design code recommendations. Consequently, their structural components, in particular beam-column joints, suffer from a wide range of deficiencies. These joints may deteriorate severely under seismic actions leading to extensive damage and collapse. The current study aims to develop an understanding of the behaviour of exterior beam-

The recent earthquakes in Christchurch have made it clear that issues exist with current RC frame design in New Zealand.

The effect of panel zone (PZ) flexibility and yielding on the stiffness and strength of steel moment resisting frames (SMRF) has been the topic of numerous papers over the past thirty years.

Due to these large inelastic deformations, the PZ region may also be a weak link in steel moment frame behavior. Because of the importance of PZ deformation in the behavior of steel frames, accurate modeling of this region is critical. Two of the most commonly used mathematical models f

Tubular columns own many structural and architectural advantages that, in certain cases, make them more favourable than open-section columns in steel moment-resisting frames. These advantages are sometimes underexploited due to the relative lack of design guidance on their moment joints to open-section beams, in particular on semi-rigid joints with special detailing for seismic actions. Different configurations of I-beam to tubular column joints have been investigated in the past, including through, internal and external diaphragm joints.

Abstract:
Reinforced concrete (RC) moment frame structures make up a notable proportion of buildings in earthquake-prone regions in the United States and throughout the world. The beam-column (BC) joints are the most crucial regions in a RC moment frame structure as any deterioration of strength and/or stiffness in these areas can lead to global collapse of the structure. Thus, accurate simulations of the joint behavior are important for assessment of the local and global performance of both one-way and two-way interior BC joints. Such simulations can be used to study the flexural-shear-bond interaction

Modern seismic design of reinforced concrete (RC) buildings is based on the capacity design principles, which provide for the dissipation of seismic energy through the development of ductile mechanism in the structural elements. Beam-column joints are critical elements, since they are governed by shear and bond behavior, with low ductility and scarce energy dissipation. In the absence of modern seismic codes prescriptions, many existing RC buildings designed before mid-1970 present structural deficiencies, like no joint shear reinforcement and the use of plain bars.

Abstract:
In the past few years, some experimental investigations have been conducted to verify seismic behaviour of fiber reinforced polymer reinforced concrete (FRP-RC) beam-column joints. Those researches were mainly focused on exterior beam-column joints without lateral beams. However, lateral beams, commonly exist in buildings, can significantly improve seismic performance of the joints. Moreover, the way the longitudinal beam bars are anchored in the joint, either using headed-end or bent bars, was not adequately addressed. This study aims to fill these gaps and investigate the shear capacity of F

Beam-column joint subassemblages is one of the important members that needed to be carefully designed to ensure when the system is subjected to strong lateral force, extensive damage does not occur in joint. Despite of having extensive research results in beam-column joint, different opinions can be found among different research groups. Given the fact that controversial opinions still exist and a few issues remain

A discussion was made through the differences in stiffness, ductility and joint shear degradation between benchmark and retrofitted specimen. From the experiment results, we found that Concrete Jacketing scheme could efficiently improve the joint shear strength and make beam plastic hinge develop before joint shear failure, which is required by the seismic resistant design code and grea

Abstract:
The entire researchers till 1970’s believed that RCC beam-column joints behave as rigid joint. So in none of the pre 1970 building codes, they had not provided the confining reinforcement in the joints. With lot of damage and destruction of building due to shear force under earthquakes most of the code committee has introduced the confinement in the joints. But recently due to use of high grade of concrete and better quality control in the RCC structures, confinements in the joints as per the new provision of codes leading to the problem of the congestion. It has been observed at many construc

Abstract:
Glass fibre-reinforced polymer (GFRP) reinforcement is used in reinforced concrete (RC) infrastructure to avoid steel corrosion problems. The behaviour of GFRP reinforcement under seismic loading in RC frame structures has not been widely investigated. The behaviour of beam-column joints significantly influences the response of the Seismic Force Resisting Systems. Therefore, both the design and detailing of the beam-column joints are critical to secure a satisfactory seismic performance of these structures. However, the current Canadian FRP design codes (CSA 2012, CSA 2006) have no considerabl
