“…Because of such advantages the precast concrete construction is being adopted world-wide including India. In precast concrete construction, connections are the most critical elements of the structure, because in past major collapse of precast building took place because of connection failure (Parastesh et al 2014, Choi et al 2013, Joshi et al 2005. Therefore it is very important to study the performance of connection between beam and column under a progressive collapse scenario.…”

Progressive collapse denotes a failure of a major portion of a structure that has been initiated by failure of a relatively small part of the structure such as failure of any vertical load carrying element (typically columns). Failure of large part of any structure will results in to substantial loss of human lives and natural resources. Therefore, it is important to prevent progressive collapse which is also known as disproportionate collapse. Now a days, there is increasing trend towards construction of buildings using precast concrete. In precast concrete construction, all the components of structures are produced in controlled environment and they are being connected appropriately at site. Connections are the most critical elements of any precast structure, because in past major collapse of precast structure took place because of connection failure. In this study, behavior of four different reduced 1/3 rd scaled precast specimens having wet and dry connections is investigated under column removal scenario and their performance is compared with monolithic connection. Precast specimens considered for the study are constructed by adopting different detailing having column with RC corbel and column with steel billet for connection with precast beam. Performance of specimen is evaluated on the basis of ultimate load carrying capacity, maximum deflection and deflection measured along the span of the beam. From the results, better performance of precast connections is observed up to elastic phase but later on strength of dry precast connections degrades more as compared to monolithic connection. Wet precast connections exhibit superior performance as compared to monolithic connection, which advocates replacement of monolithic connection with appropriate connection detailing. From the results, is also observed that precast connections constructed using RC corbel performs better as compared to those constructed using steel billet. Structures Congress 2015 1101

Precast concrete construction is being adopted worldwide including India during recent past. In precast concrete construction all the components of structures are produced in controlled environment and it is being transported to the site. At site such individual components are connected appropriately. This leads to many advantages like minimizing cast in place concrete, reduced amount of waste, less requirement of formwork, scaffolding and skilled labors, massive production with better quality, faster construction etc. But connections are the most critical elements of any precast structure, because in past major collapse of precast structure was taken place because of connection failure. In this study, behavior of two different exterior reduced scaled dry precast beam column was studied and its performance is compared with their monolithic counterpart. Precast connections are constructed by using cleat angles stiffened with single stiffener and double stiffeners for connections between beam and column. Performance of specimen is evaluated on the basis of ultimate load carrying capacity, maximum deflection. The deflection is measured along the length of the beam. From the results, it is observed that precast connections are capable to produce ductile behavior but load carrying capacity is lesser than that of the monolithic connection.

“…These types of joints are well known because of minimum site work, such as welding and bolting. Khoo, Li, and Yip [9], Xue and Yang [10], Khaloo and Parastesh [11], and Parastesh, Hajirasouliha, and Ramezani [12] have studied this type of joint. Diaphragms are another member of precast concrete structures that are extensively used in transferring and carrying load.…”
