They are used in building construction, as siding, ceilings, floors, roofs and tile backer boards. The cellulose fiber cement siding is commonly used as a replacement for wood siding, as it is less expensive and more durable, and has lower maintenance costs [1]. The FCB al...

The oral rehabilitation of edentulous patients with immediate loading has become a safe procedure with high predictability. The success is related to immediate fabrication of a passive fit framework to attach the implants. Based on these considerations, this case report shows an alternative technique for mandibular rehabilitation using implants immediately loaded, where the framework was fabric...

The short-line match-cast joint method of pre-casting concrete segments has proved to be the most versatile and reliable way to building pre-cast segmental bridges. The essential feature of match casting is that successive segments are cast against adjoining segment in the correct relative orientation with each other starting from the first segment away from the pier. The segments are subsequen...

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...

This article presents a damage detection method for prestressed reinforced concrete (PRC) elements based on free vibration tests and nonlinear damping identification. Integrated static and dynamic experiments were carried out on three precast PRC beam specimens. The static loading induced different levels of damage to the beams. At each damage level, impulsive loading was applied to the beams a...

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 ...

Building Information Modeling realm is expanding with the advent of new technologies, processes and software for Architecture, Engineering, Construction and Facility Management industry. The importance of robust knowledge sharing between different stakeholders in a project is of highest priority in such scenarios. model diew definitions provides an empirical specification for the implementation...

This paper describes a project with the aim of reducing the risk of injury when using precast concrete shells in the Swedish construction industry by identifying injury risks, developing and implementing solutions. An interactive research approach was used. Three major injury risks were identified and a system consisting of three tools and a handbook was developed, evaluated, and implemented at...

The performance of the grouted sleeve lapping connector that is used to connect reinforcement bars in a precast concrete structure is studied. A total of 63 specimens, varying in bar diameter and lap length, were tested under tensile load. The failure modes, ultimate tensile strength values and load-displacement curves of the specimens are discussed in the study. Two equations are proposed for ...

Self-consolidating concrete (SCC) mixtures designated for precast, prestressed applications should be highly workable to flow easily through restricted spacing and completely encapsulate reinforcements without any mechanical vibration. Key workability characteristics of SCC can be described in terms of filling ability, passing ability, and resistance to segregation. These properties are typical...
