National Annex (informative) to BS EN 1992-2:2005, Eurocode 2: Design of concrete structures – Part 2: Concrete bridges – Design and detailing rules. Introduction. This National Annex has been prepared by BSI Subcommittee B/525/2 Structural use of concrete. In the UK it is to be used in conjunction with BS EN 1992-2:2005. NA.1 Scope

The structure of the anti-lateral force system which is composed of a frame and a bracing. 2.1.19 Frame braced with strong bracing system In the frame-bracing structure, if the bracing structure (bracing truss, shear wall, cylinder, etc.) has a large lateral stiffness resistance, the frame can be regarded as a frame without lateral displacement.

The effects of prestressed cables in composite structural system were studied [4]. In recent years, experimental study and numerical analysis have been carried out on composite space trusses with prestressed cables made of steel and compression members made of concrete [5,6].

PRESTRESSED CONCRETE Prestressed concrete, invented by Eugene Frevssinet in 1928 is a method for overcoming concrete’’s natural weakness in tension . It can be used to produce beams , floors or bridges with a longer span than is practical with ordinary reinforced concrete. It can be accomplished in three ways: pre- tensioned concrete, and

mations for design of reinforced and prestressed concrete. It is noted that truss models can only be used to design regions of a concrete structure where the Bernoulli hypothesis of plane strain distribution is assumed valid. At regions where the strain distri-bution is significantly nonlinear, the truss model theory is not applicable.

Deflection check of reinforced and prestressed concrete girders with the effect of cracking, concrete age (modulus of elasticity), creep, and shrinkage. Detailing rules Minimum and maximum reinforcement areas, spacing of longitudinal bars and shear reinforcement, limit value of tendon stress. etc.

The invention relates to a method for reinforcing a bridge structure separated steel-concrete combined truss. The method is characterized by comprising the following steps of: 1, processing an interface at the joint of upper and lower flanges of a concrete beam; 2, planting steel bars in concrete at the joint of the upper and lower flanges of the concrete beam; 3, manufacturing steel plates

A prestressed concrete structure is different from a conventional reinforced concrete structure due to the application of an initial load on the structure prior to its use. The initial load or ‘prestress’ is applied to enable the structure to counteract the stresses arising during its service period.

A total pre cast prestressed concrete structure might combine structural prestressed steel reinforced concrete beams, columns, double “t”s or hollow core slabs with insulated wall panels, spandrels or architectural precast panels to construct buildings with both form and function.
