A reinforced concrete column is a structural member designed to carry compressive loads, composed of concrete with an embedded steel frame to provide reinforcement. For design purposes, the columns are separated into two categories: short columns and slender columns.
A large number of Indian Standard (IS) codes are available that are meant for virtually every aspect of civil engineering one can think of. During one's professional life one normally uses only a handful of them depending on the nature of work they are involved in. Civil engineers engaged in construction activities of large projects usually have to refer to a good number of IS codes as such ...
Initiation and propagation periods of steel rebar corrosion in a reinforced concrete structure (Tutti diagram). [2] [3] Initially, the chemical reactions that normally occur in the cement paste, generate an alkaline environment, bringing the solution in the cement paste pores to pH values around 13. In these conditions, passivation of steel ...
Logo of Eurocode 2 An example of a concrete structure. In the Eurocode series of European standards (EN) related to construction, Eurocode 2: Design of concrete structures (abbreviated EN 1992 or, informally, EC 2) specifies technical rules for the design of concrete, reinforced concrete and prestressed concrete structures, using the limit state design philosophy.
Concrete and steel reinforcement bars combine to create strong, resilient structures in the following ways: Upon contact with each other, the cement paste and steel rebar form a non-reactive surface film preventing corrosion. Reinforcement bars or beams can be strategically set throughout the concrete to achieve the required support system.
Reinforced concrete, also called ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility.
A walkout by baristas at Starbucks expanded on Tuesday, as more workers joined at five-day labor action against the coffee giant in a protest that comes to a close later in the day.
The portion of the beam that is in tension may crack. The size and length of cracks is dependent on the magnitude of the bending moment and the design of the reinforcing in the beam at the point under consideration. Reinforced concrete beams are designed to crack in tension rather than in compression.
