“…straight spliced, U-shaped spliced and U-shape spliced with steel plates within connection zone which was part of 5-storey frame under reverse cyclic loading and compared its performance with monolithic connections. Choi et al [5] proposed design of precast beam column connections using steel connectors constructed by bolting steel tubes and steel plates fixed within precast components was suggested based on the results of cyclic load tests performed on five half scale interior precast beam column assemblies. Maya et al [6] recommended new beam column connection for precast construction using Ultra High Performance Fibre Reinforced Concrete (UHPFRC) to achieve shorter splice length.…”

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.

“…However, most of the researches on insulation methods so far have been conducted under the purpose of improving the sandwich panel method that are actively applied for low-rise buildings construction [35][36][37][38][39] and approached the external insulation system in terms of thermal engineering and building materials. Studies conducted for improving the construction aspect of external insulation system are highly limited.…”

External Insulation Finishing System (EIFS) is recognized as a suitable method for attaining energy efficiency of buildings. However, conventional EIFS is not actively applied to building construction due to additional time and cost compared with interior insulation method. Therefore, as an alternative that can contribute to active utilization of the external insulation system, this study proposes an External Insulated Precast Concrete (PC) Wall System and its simulation for performing productivity analysis. Results of this study are as follows: (1) an external insulated PC-Wall system is developed of which its insulation performance is above 40% higher than that of the conventional EIFS; (2) performance of the developed system satisfied American Standards for Testing of Materials (ASTM) and American Architectural Manufacturers Association (AAMA) standards; (3) applicability of the developed system is verified via test-bed with construction time lapsing about 40 min for each PC-Wall; and (4) CYCLONE modeling methodology is employed to perform productivity analysis of the developed system compared with conventional EIFS.

The objective of a present work is to compare an experimental and analytical study on precast frame. A precast frame development includes the whole structural components being manufactured off-site. Connection is the crucial part in precast frame because it influences the performance of structural behavior. There are various connections in the beam -column, out of which grout connection are chosen in this study. A scale model is created for the identified critical bay. A precast frame are constructed and tested under loading condition. The parameters considered for the present study are Ultimate Load Carrying Capacity, Cracking Pattern and Failure Mode, Load Displacement behavior and Energy Dissipation Capacity. The analytical study of the precast frame which are done by ANSYS software. After analyzing a frame in Ansys, both experimental and analytical works are compared in this paper.
