Design Considerations for the Connection of Precast Concrete Structures
The structural integrity of precast concrete buildings depends mainly on the connections between the precast structural components. Large precast concrete panels are used extensively in North America for low, medium, and highrise construction due to their ease and speed of assembly, and high quality control. This paper presents the results of twenty-two prototype specimens tested to investigate...
متن کاملPerformance of the Modified Precast Beam to Column Connection Placed on a Concrete Corbel
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 ...
متن کاملAdvantages of Large Strands in Precast/Prestressed Concrete Highway Application
The objective of this research is to investigate the advantages of using large-diameter 0.7 inch prestressing strands in pretention applications. The advantages of large-diameter strands are mainly beneficial in the heavy construction applications. Bridges and tunnels are subjected to a higher daily traffic with an exponential increase in trucks ultimate weight, which raise the demand for highe...
متن کاملPrecast Concrete Elements
Lattice-girder floor slabs and double-wall elements have been successfully used in building and industrial construction for decades. These precast elements of 50 – 70 mm thickness serve as permanent formwork for the subsequently added in-situ concrete creating a monolithic structure. The high prefabrication level allows the construction period to be significantly minimized. The main goal is the...
متن کاملSimulation in Large-scale Precast Operations
This document details a rationalisation study on the production of shop-prefabricated parts supported by simulation to analyse potential operating alternatives. The goal was quite specific: to improve productivity and so reduce production costs. Since the study was carried out while the workshop was fully operational, no changes that would have involved stoppages in workshop production could be...
