Lateral Pressure Test of Vertical Joint Concrete and Formwork Optimization Design for Monolithic Precast Concrete Structure

Precast Concrete Elements

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...

Design Considerations for the Connection of Precast Concrete Structures

The structural integrity of precast concrete buildings depends mainly on the connections between the precast structural components. Large precast concrete panels are used extensively in North America for low, medium, and highrise construction due to their ease and speed of assembly, and high quality control. This paper presents the results of twenty-two prototype specimens tested to investigate...

Design of Hybrid Precast Concrete Walls for Seismic Regions

This paper presents an ongoing research project on the behavior and design of “hybrid” precast concrete wall structures for use in seismic regions. Hybrid precast walls utilize a combination of mild (e.g., Grade 60) steel and high-strength unbonded post-tensioning (PT) steel for flexural resistance across horizontal joints. The mild steel reinforcement is designed to yield in tension and compre...

Experimental Study on Flexural Behavior of Precast Concrete Shear Walls with Vertical Joint

Seismic Design Considerations for Precast Concrete Shear Wall Connections

The performance of precast shear wall panel structures subjected to earthquakes relies on the behaviour and integrity of the connections between the panels. The current lack of knowledge on the seismic behaviour of precast wall connections limits the use of such systems in earthquake areas. This paper presents results of an extensive experimental program undertaken at the University of Manitoba...
