,Reinforced concrete beams—the ultimate limit state, basis of the elastic theory. In reinforced concrete beams, in addition to the effects of shrinkage and creep and of loading history, there are the uncertain effects of the cracking of the concrete in the tension zone; as in columns, conventional calculations for the stresses in reinforced concrete

Shear, bond and torsion,e governed by flexure rather than by shear [1, 2]. Shear failures, which in reality are failures under combined shear forces and bending moments, are characterized by small deflections and lack of ductility. There is sometimes little warning before failure occurs, and this makes shear failures parti

Eccentrically loaded columns and slender columns,rengths in Chapter 4. The member is considered to be at the ultimate limit state of collapse when the concrete strain at the more highly compressed face reaches a specified value ε., which is taken as 0.0035 in current British practice.

省略

Prestressed concrete simple beams,is necessary for the structural engineer. Prestressed concrete may be defined as concrete in which internal stresses of such magnitude and distribution have been introduced that the stresses resulting from the given applied loading are counteracted to a desired degree.

完整

Prestressed concrete continuous beams,port reactions. Consider the simple beam in Fig. 10.1-1(a). If for the time being, we do not consider the effects of the dead and imposed loads, then whatever the magnitude of the prestressing force and the tendon profile, there will be no reactions at the supports A and B.* Of course, the prestress

Inordinate

Practical design and detailing,o mean the formulation, in the mind, of some scheme or plan. This normally entails a proposition followed by some form of analysis which either proves or disproves the original proposition. The formulation of the original idea is usually based on experience and, therefore, the structural engineering
