Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection and the overall integrity of the structure. This paper presents the results of a research program conducted to investigate ...

This paper presents an experimental evaluation of the flexural response non-load bearing precast concrete insulated partially-composite wall panels fabricated with varying layouts ductile shear ties. The out-of-plane, one-way, single span load-displacement relationship is obtained for each panel via pseudo-static testing using a water bladder apparatus. Panel specimens constructed several tie a...

and findings of laboratory and field tests of a new generation of precast composite piles used for the first time in the construction of the Route 40 highway bridge over the Nottoway River in Virginia. The piles consisted of 24.6 in. (625 mm) diameter concrete-filled glass fiber reinforced polymer (GFRP) circular tubes, with a 0.21 in. (5.3 mm) wall thickness. The composite piles extended above...

The Precast Concrete Industry (PCI) is one of the major contributors to the national economy and can be categorised as labor-intensive industry. It is currently experiencing shortcomings in terms of delivery products at a competitive cost and time. This is mainly due to the inefficiencies associate with planning and scheduling of skilled operators within crews configurations. This paper present...

In recent decades, steel frames infilled with precast load-bearing walls have been successfully employed as lateral load-resisting structural systems in high-rise buildings. This is due to their efficiency outer and major inner facades the higher construction speed of building. paper presents a detailed experimental investigation sustainable, prefabricated, composite wall system, using represen...

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...

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...

Precast concrete material suppliers are responsible for the components that they manufacture from casting until up to 25 years after installation. To effectively manage the production and storage at a the production facility, to streamline the construction process and to quickly repair a component should there be a problem, information about components must be readily available and updated thro...

This study investigated the seismic performance of cementitious grout filled coupler and sleeve connections in precast wall panels under cyclic lateral loading. The effectiveness these enhancing concrete walls was evaluated. In many countries, grouted are preferred option, whereas were more commonly utilized India due to belief that a greater portion dowel being enhances structural stability. T...
