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...

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...

Abstract: Shear deformation is the most principal deformation in the lateral deformation of shear wall built with precast hollow slab which is designed to be strong shearing and weak bending. The special mechanical characteristic of the shear wall is the relative deformation of the concrete on both sides of vertical and inner joint respectively. The study introduces the measuring scheme of shea...

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...

Prefabricated modular housing structures have become a promising alternative to site-built structures with equal or higher engineering quality and durability. Major advantages of this technology are fast and cost-efficient construction, reduced labor requirements, and superior quality control due to factory production. The modular design of these prefabricated structures offers the opportunity ...

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 ...
