Precast Concrete Floors in Steel Framed Buildings

What Is Concrete Frame? | What Is Precast Concrete Frames

Frame structures of different types of buildings can be made from different materials like steel, reinforced concrete, and wood. The frame structure of a building is made up of components such as beams, columns, and slabs to resist external and gravitational loads coming over it.

The floor and roof system of the superstructure is precast hollow core concrete plank on steel framing. The concrete planks are HD265's and have approximate section dimensions of 1.2m x 0.3m (figure 3). Spans range from 5m to 10m and are run in the East-West direction. Due to the buildings shape, edges of some of the planks are cut at an angle.

Precast concrete - Wikipedia

Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and lifted into place ("tilt up"). In contrast, cast-in-place concrete is poured into site-specific forms and cured on site. Precast stone is distinguished from precast concrete using a fine aggregate in the
