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.
EN 1992-1-2 deals with the design of concrete structures for the accidental situation of fire exposure and is intended to be used in conjunction with EN 1992-1-1 and EN 1991-1-2. This part 1-2 only identifies differences from, or supplements to, normal temperature design. Part 1-2 of EN 1992 deals only with passive methods of fire protection.
Large crack-widths (greater than 0.3 mm) permit ingress of moisture and chemical attack to the concrete, resulting in possible corrosion of reinforcement and deterioration of concrete. Therefore, thick covers defeat the very purpose for which it is provided. There is a need for judicious balance of cover depth and crack width requirements.
The strength enhancing effects of arching action in reinforced concrete floors were first recognised near the beginning of last century. [1] However, it was not until the full scale destructive load tests by Ockleston [ 2 ] [ 3 ] on the Old Dental Hospital in Johannesburg that the extent of strength enhancement caused by arching action was ...
The Richards’ commitment to the festive season is evident in their hefty investment in decorations and energy costs that ran them about $2,291 per month. 4. Paul Bibby’s Tribute Display ...
Luigi Mangione, the man accused of murdering UnitedHealthcare CEO Brian Thompson, was told "don't say a word" by his lawyer in court, following an outburst outside the hearing at a Pennsylvania ...
When the reinforced concrete element is subject to increasing bending moment, the tension steel yields while the concrete does not reach its ultimate failure condition. As the tension steel yields and stretches, an "under-reinforced" concrete also yields in a ductile manner, exhibiting a large deformation and warning before its ultimate failure.
