Precast concrete structures in Iran are generally designed as continuous columns with hinged beams, thereby making them simple frames. In this system in site show walls in two directions of buildings guaranteed lateral resisting system. However, in order to obtain a seismic resisting frame, the connection between beam and column should be moment resisting and ductile, allowing the formation of ...
the present study focuses on the performance of precast concrete beam-column dowel connections subjected to cyclic loading by conducting experiments. in this study, one-third scale model of two types of precast and a monolithic beam-column connection were cast and tested under reverse cyclic loading. the precast connections considered for this study is a beam-column connection where beam is con...
Comparing Repaired and Undamaged Specimens Test Results of Post-Tensioned Beam to Column Connections
Since, it is essential to provide homeless people by the earthquake with safe, habitable accommodation repairing medium and slight levels of damage at the connection parts should be undertaken. In order to prove that a repaired connection was sufficiently strong, a precast beam to column post tensioned connection was tested in three phases. In phase one, the middle level damage was observed at ...
Following the Northridge earthquake of 1994, a significant number of steel moment resisting structural systems were damaged. Several studies have been conducted to improve the seismic performance of steel structures and specially their beam-to-column connections. One of the proposed connections for special moment-resisting frames included AISC-358 is Kaiser bolted bracket moment connection, bri...
The 2012 Emilia earthquakes caused significant damage to existing precast reinforced concrete (RC) industrial buildings not specifically designed resist seismic actions. main failure mechanisms were related the loss of support beams and roof elements by high relative displacements, mechanical connections consequent fall cladding panels, at base columns collapse RC forks top columns. In all case...
Accelerated bridge construction (ABC) has attracted much attention in China as a new and efficient method. However, the seismic performance of connections between precast piers other structures limits application ABC medium high zones. In this paper, quasi-static test was conducted to investigate differences cap–column socket connection (PSC) specimen, which reinforced an embedded RC column-to-...
a parametrik investigation was conducted to study the non-linear behavior of precast and cast-in-place reinforced concrete beam-column connections subjected to tabas seismic forces (1979). the behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. calculation result...
The worldwide use of precast concrete frames leads to an increase in the need for the investigation of efficient precast connections, particularly in the seismic regions. The current paper provides a numerical and experimental study on a dry precast connection. Experiments were conducted to validate the finite element method in the laboratory of the University of Science and Culture. To verify ...
