Precast Concrete Floor, Wall and Frame Construction Process

types of precast concrete upper floor construction

precast concrete composite flooring is a high quality economical concrete floor construction where long spans and/or high load bearing capacities are required. suspended concrete floors are constructed using prestressed planks supported by either masonry walls or a supporting steel frame structure.

Precast Concrete Construction | Uses and Types of Precast

A precast wall is an ideal solution for providing stability to a frame structure that can carry vertical loads. Most construction companies use precast walls with floor slabs to form a complete structure. The precast walls are a suitable one for enhancing the stability to a building thereby showing ways for ensuring optimal results.

PRECAST CONCRETE CONSTRUCTION AND SEISMIC DESIGN There is a general concern regarding the seismic performance of precast construction. It is noticed that large panel construction performs better than frame system. However, in areas of high seismic risk, structures must be designed to respond safely to the dynamic forces imparted into the structure.

Construction Incidents Investigation Engineering Reports

A partially erected precast concrete frame of the 3,300 car parking garage suddenly collapsed. The structural design was hybrid: precast concrete columns and beams, and cast-in-place post-tensioned floors. The collapsed frame was approximately 65' long, 56' wide and 80' high weighing approximately 900 tons. Two workers were injured.

Foundation Options | Concrete Lower Columns by Morton

Extend the life of your building by using concrete lower columns in your foundation, rather than wood. The evolution of post-frame construction is here—remove wood from the ground to create the strongest and most durable building yet. Morton Buildings is committed to building all new structures, when possible, without wood in the ground.

Filigree concrete - Wikipedia

The Filigree Wideslab method is a process for construction of concrete floor decks from two interconnected concrete placements, one precast in a factory, and the other done in the field. The method was developed during the late 1960s by Harry H. Wise as a more efficient and economic construction process than conventional cast-in-place technologies.
