· This course will limit discussion to normal reinforced structural concrete using 4,000 psi concrete and 60,000 psi rebar. There are two acceptable methods to design concrete: the working stress method and the ultimate strength method. The ultimate stress method is the one most commonly used.
· Once the formwork has been nailed around the rebar, mix the concrete. Pay attention to the concrete mix since the ratio of water to mortar will determine the functionality and strength of the pillar. Pour the concrete into the formwork. Once the concrete has sufficiently solidified, remove the formwork. This process can take several days.
Rebar tying requirements R e i n f o r cing bars are tied together to form a rigid mat for footings, walls, and slabs. A rigid cage is formed when beam or column longitudinals a r e tied to the stirrups and ties. Iro n - workers usually tie a minimum num-ber of rebar intersections. If the speci-fications are not precise about the

AsktheBuilder.com: Concrete piers are vertical structural elements that support the weight of a building or structure. Their design and installation must consider the weight being supported and the frost line in your area. There are preformed concrete pier forms that provide you with the properly shaped concrete pier foundation.

· Detailing Concrete Columns D esigners of concrete structures are typically concerned about the final design and not necessarily about how a specific concrete element gets built. In other words, engineers tend to avoid issues that are traditionally contractor "means and methods." Yet, decisions made during the design process can have

· ARCH 631 Note Set 10.1 F2013abn 3 Reinforced concrete is a composite material, and the average density is considered to be 150 lb/ft3. It has the properties that it will creep (deformation with long term load) and shrink (a result of
· continuity and adequate anchorage for rebar of ties have been provided. Fuller discussion is included in Section 14 of this Manual. Wind loads for design should be taken from Code of Practice on Wind Effects in Hong Kong 2004. It should also be noted that there are differences between Table 2.1 of the
· All the quantities are shown per m3 of concrete. The typical density of concrete is approximately 2400 kg /m3. Tendon* = high strength low allow steel, typically used for instance in pre-stressed concrete elements, this steel grade is likely to contain more virgin steel Rebar steel* = basic steel used for concrete reinforcement.
Once the formwork has been nailed around the rebar, mix the concrete. Pay attention to the concrete mix since the ratio of water to mortar will determine the functionality and strength of the pillar. Pour the concrete into the formwork. Once the concrete has sufficiently solidified, remove the formwork. This process can take several days.
