  2. Curb cut - Wikipedia

    en.wikipedia.org/wiki/Curb_cut

    A pram ramp with tactile paving that connects a sidewalk to a road. A curb cut , curb ramp, depressed curb, dropped kerb , pram ramp, or kerb ramp is a solid (usually concrete) ramp graded down from the top surface of a sidewalk to the surface of an adjoining street. It is designed primarily for pedestrian usage and commonly found in urban ...

  3. Lift slab construction - Wikipedia

    en.wikipedia.org/wiki/Lift_slab_construction

    Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...

  4. Reinforced concrete structures durability - Wikipedia

    en.wikipedia.org/wiki/Reinforced_concrete...

    The durability design of reinforced concrete structures has been recently introduced in national and international regulations. It is required that structures are designed to preserve their characteristics during the service life, avoiding premature failure and the need of extraordinary maintenance and restoration works.

  5. Reinforced solid - Wikipedia

    en.wikipedia.org/wiki/Reinforced_solid

    The reinforcement is directed in the x, y and z direction. The reinforcement ratio is defined in a cross-section of a reinforcing bar as the reinforcement area over the total area , which is the brittle material area plus the reinforcement area.

  6. Prestressed concrete - Wikipedia

    en.wikipedia.org/wiki/Prestressed_concrete

    By the 1960s, prestressed concrete largely superseded reinforced concrete bridges in the UK, with box girders being the dominant form. [ 41 ] In short-span bridges of around 10 to 40 metres (30 to 130 ft), prestressing is commonly employed in the form of precast pre-tensioned girders or planks. [ 42 ]

    The first residential building of slipform construction; erected in 1950 in Västertorp, Sweden, by AB Bygging Later picture of the residential building in Västertorp. Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is placed into a form that may be in continuous motion horizontally, or incrementally raised vertically.

  8. Joseph Monier - Wikipedia

    en.wikipedia.org/wiki/Joseph_Monier

    But if a concrete slab is reinforced with a network of small steel rods on its undersurface where the tensile stresses occur, its strength will be enormously increased. François Hennébique saw Monier's reinforced concrete tubs and tanks at the Paris Exposition and began experimenting with ways to apply this new material to building ...

  9. Waffle slab - Wikipedia

    en.wikipedia.org/wiki/Waffle_slab

    The name waffle comes from the grid pattern created by the reinforcing ribs. Waffle slabs are preferred for spans greater than 40 feet (12 m), because, for a given mass of concrete, they are much stronger than flat slabs, flat slabs with drop panels, two-way slabs, one-way slabs, and one-way joist slabs.
