For normal weight concrete (defined as concrete with a w c of 150 lb/ft 3 and subtracting 5 lb/ft 3 for steel) E c is permitted to be taken as ′. The publication used by structural bridge engineers is the AASHTO Load and Resistance Factor Design Manual, or "LRFD."
Reinforcing rebar is placed axially in the column to provide additional axial stiffness. Accounting for the additional stiffness of the steel, the nominal loading capacity P n for the column in terms of the maximum compressive stress of the concrete f c ' , the yield stress of the steel f y , the gross cross section area of the column A g , and ...
The weight of the element can be determined by the calculated volume, and using the specific gravity (normal weight reinforced concrete is approximately 24 kN/m3). Establishing the lifting anchor positions will influence the rigging arrangements used and therefore the static analysis of the rigging should be determined.
The standard that covers CE Marking of structural steelwork is EN 1090-1. The standard has come into force in late 2010. After a transition period of two years, CE Marking will become mandatory in most European Countries sometime early in 2012. [8] The official end date of the transition period is July 1, 2014.

Once this is defined, design code gives standard prescriptions for w/c ratio, the cement content, and the thickness of the concrete cover. This approach represents an improvement step for the durability design of reinforced concrete structures, it is suitable for the design of ordinary structures designed with traditional materials (Portland ...
