extreme fiber stresses at the mid section of the beam a pre-stressed concrete beam of cross section 300 mm x 500 mm and 8 m is
state the term - transverse force on concretewe know that in pre-stressed concrete tendons are placed in a stretched condition and they always would
concept of load balancingin above cases of concentric and eccentric pre-stressing straight tendon profiles or tendon shapes along the beam have
what do you understand by pressure lineif we determine the locations of resultant force at various sections of a pre-stressed beam as in example we
enumerate the term - superposing the stress variations if the case of concentric pre-stressing is considered we can appreciate that stress at any
resultant force at a sectionwe can determine stresses at top and bottom fibres at a section of a beam due to pre-stressing force and external loads

how to calculate the total loss of prestressas a general guide it may be taken that total loss of prestress may be in the range of 20 to 25 percent
categories of losses of prestresswe may put various losses in either of two categories losses which take place during transfer of prestress and
total loss of prestress the total amount of losses of prestresses may be accounted for in a prestressed concrete member by adding different losses
