The rehabilitation of structures is a complex process that involves many considerations. This paper presents results feasibility study on the use precast prestressed concrete prisms (PCPs) as near-surface mounted reinforcement for cracked one-way slabs. PCPs were cast with high-strength and concentrically by one 9 mm diameter stress-relieved seven-wire steel strand. Six identical slabs length 3...

This article reviews a method for generating a product model from user data and introduces 12 design patterns for resolving conflicts that may occur in the integration and normalization process. The generating method and design patterns were evaluated during a project to integrate the product models collected from three different precast concrete companies in the United States, testing the new ...

We review the transition now being undertaken from 2D drafting to 3D parametric modeling and the development of Building Information Modeling (BIM). We examine the functionality of BIM platforms, using an example from precast concrete structures. We formulate the development of parametric modeling of building systems from the context of SFB modeling and characterize most parametric modeling as ...

Several of the texts on prestressed concrete illustrate the magnitude of the effect of prestressing on the concrete by using a fishing pole as an example. As I recall the fishing pole described, it consists of a length of concrete one inch square in section with a single wire pretensioned through and along its central axis. Not until I was to witness the behavior of the massive precast, postten...

Naturally occurring carbonation of cement-based materials is a slow phenomenon. Many factors control the rate of carbonation process in cement-based products. A comprehensive knowledge of the major factors controlling the rate of carbonation, and their effects on the properties of the materials subjected to it, is necessary for using this technology for CO2 sequestration. Most of the studies re...

The strength of Ultra-High Performance Concrete (UHPC) can be sensitively affected by the curing method used. However, in contrast to the precast plant production of UHPC where a standard high-temperature steam curing is available, an optimum curing condition is rarely realized with cast-in-place UHPC. Therefore, the trend of the compressive strength development of UHPC was experimentally inves...

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 ...
