1.1. The History of Precast Building Precast building has always been a challenge in terms of the attempt to build buildings, above all, more quickly, whilst at the same time meeting all the conditions of good quality construction. This paper deals with the precast mode of construction using a timber frame, of the panel type, suitable for buildings with 3-4 storeys above ground. Therefore, in t...

Nowadays precast concrete elements are widely used in buildings, bridges, and other civil infrastructure facilities because precast elements allow rapid construction and high precision quality control. However, the quality inspection of precast concrete elements primarily relies on manual inspection, which is time consuming and error-prone. Recently, terrestrial laser scanner (TLS) has been use...

ABSTRACT: With the advent of precast construction technology, the construction industry has seen a rapid change in the way structures are built. Precast construction has brought down project costs and durations, increased the predictability and improved the quality of construction. It has also resulted in a shift in construction tasks from the construction site to the factory floor. Precast ele...

The main objective of the present work is to study the present situation of the precast construction industry in India. Suggestions for improvement of the industry and study on cost effectiveness of precast concrete construction for single and multi-story residential buildings are to be given. A literature survey was carried out in order to obtain the comparison between the conventional buildin...

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 ...

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 ...

PCI JOURNAL This paper presents the results of nonlinear fi nite element analyses conducted to model the behavior of L-shaped, precast, prestressed concrete spandrels constructed with open web reinforcement. The fi nite element model was calibrated using experimental results from recent tests of slender, L-shaped, precast, prestressed concrete spandrels. Detailed correlative studies between ana...

Research Question: Is the lean production philosophy applicable in precast concrete factories to achieve sustainability? If it is, what are the imperfections that can be improved to achieve sustainability? Purpose: This study aims to identify the contribution of the lean concept to achieve sustainability in precast concrete factories. By using appropriate lean principles, the precast concrete i...

We report on a large-scale effort to integrate advanced design and engineering information technologies (IT) in the North American precast/prestressed concrete industry. The effort has been undertaken by a consortium of precast producer companies formed specifically for the task. The effort involved significant process modeling work, using a unique method and set of tools. It led to the develop...

This paper presents several advancements in the use of fiber reinforced polymer (FRP) materials for the precast concrete industry. Precast concrete members are commonly selected for reasons such as the high level of quality control used in their production, the durability of the finished structure, reduced labor costs and shorter construction schedules, and the economics of scale achieved with ...
