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.
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 ...
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.
Musk also met on Nov. 11 with Iran's ambassador to the United States in an effort to help defuse tensions between the two countries, according to multiple reports. Iran later denied that the ...

Days of protests have rocked Georgia following the government’s controversial decision to delay the former Soviet country’s bid to join the European Union.
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 really ...
