CALCULATION OF BENDING MOMENT DUE TO TEMPERATURE CHANGE.     PROGRAM INFO AND LIMITATIONS.
( Actual program is available in Super Civil CD )
The calculation of bending moment due to temperature change in concrete wall is based on       Reynolds  &  Steedman Concrete  Hand Book .  Please note that the bending moment due to       change in temperature produces compression on  the face subjected to the higher       temperature. This program is applicable to walls where there is temp. gradient, and not       when there is a  uniform raise in temperature. 
 The un-cracked depth of concrete shall be given , whenever the design is not based on
      IS 3370 (Code of Practice for liquid retaining structures). This un-cracked concrete depth is       distance between extreme fiber in compression to neutral axis. In case the design is based on       un-crack section , the un-crack depth of section will be equal to full depth.
 Contribution of       reinforcement in calculation of moment of inertia of un-cracked section is  neglected. After       getting the BM. due to temperature change a user has to add this moment algebraically
      to
other externally applied BM.
The K, Density, &  Temp. Of  Various Insulation Materials are given for reference.
