In this method the reinforcing steel is first prestressed and then the concrete is poured. When the concrete has developed strength, the stress in the steel is released.
Pre-tensioning or bonded prestressing.
Post-tensioning or unbonded pre-stressing.
Pre-Cast
Cast-In Place
In this method, tubes, conduits, or channels are inserted in the concrete where reinforcing steel is required.
Pre-tensioning or bonded prestressing.
Cast In Place
Pre Cast
Post-tensioning or unbonded pre-stressing.
It is a modern building method that is based in the combination of steel cross sections and reinforced concrete elements and is aimed at the maximum possible utilization of their properties to the benefit of the structure.
Conventional Construction
Composite Construction
Cast-In Place Construction
Pre-Engineered Buildings
Consists of panels and components that are pre-fabricated in a factory, and transported to the construction site ready to be assembled.
Lateral Systems
Open Web Steel Joist
Pre-Engineered Metal Buildings
Cold Rolled Steel Sections
What type of lateral system are shown in the illustration?
Shear Wall
Cross Bracing
Chevron Bracing
Rigid Frame
This type of lateral load-resisting system engages a vertical element of the building, usually concrete or masonry, to transfer the horizontal forces to the ground by a primary shear behavior.
Shear Wall
Cross Bracing
Chevron Bracing
Rigid Frames
Widely used in the pre-engineered metal building (PEMB) industry mainly as roof and floor support systems. Their capacity to sustain loads with long span and lightweight configurations gives this system a great advantage over conventional wide flange steel beams and girders in the industry.
Cold-Rolled Steel Sections
Open Web Steel Joists (OWSJ)
Pre-Engineered Metal Buildings
Pin-Joint Steel Frames
Serves as a permanent formwork for a reinforced concrete slab until the slab can support itself and its live load.
Form Decking
Composite Decking
Cellular Decking
Metal Decking
is manufactured by welding a corrugated sheet to a flat steel sheet, forming a series of spaces or raceways for electrical and communications wiring; special cutouts are available for floor outlets. The decking may serve as an acoustic ceiling when the perforated cells are filled with glass fiber.
Metal Decking
Form Decking
Cellular Decking
Composite Decking
Serves as a tensile reinforcement for the concrete slab to which it is bonded with embossed rib pattern.
Composite Decking
Form Decking
Cellular Decking
Metal Decking
is defined a pin-joined system with a particular configuration of cables
and struts that form a statically indeterminate structure in a stable equilibrium. Infinitesimal mechanism should exist in a tensegrity with equivalent self-stress state.
