The engineering study of every reinforced concrete construction, whether it is a building, a bridge, a bearing wall, or another structure, dictates the positioning of steel rebars at specific positions in the volume of concrete (predicted concrete cover of steel reinforcement bars). This cover varies between 10 mm and 100 mm.
Metal formwork systems are better protected against rot and fire than traditional timber formwork. Re-usable plastic formwork. These interlocking and modular systems are used to build widely variable, but relatively simple, concrete structures. The panels are lightweight and very robust.
G. A. Wayss was a German civil engineer and a pioneer of the iron and steel concrete construction. In 1879, Wayss bought the German rights to Monier's patents and, in 1884, his firm, Wayss & Freytag, made the first commercial use of reinforced concrete. Up until the 1890s, Wayss and his firm greatly contributed to the advancement of Monier's ...
Concrete shear walls are reinforced with both horizontal and vertical reinforcement (Figure 4). A reinforcement ratio is defined as the ratio of the gross concrete area for a section taken orthogonal to the reinforcement. Construction codes of practice define maximum and minimum amounts of reinforcement as well as the detailing of steel bars.
In the event of inelastic response, steel panels are more readily replaced, and repairs are otherwise more simple than for equivalent reinforced-concrete systems. In comparison with conventional bracing systems, steel panels have the advantage of being a redundant, continuous system exhibiting relatively stable and ductile behaviour under ...
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 maneuvered into place; examples include precast beams, and wall panels, floors, roofs, and piles.
