Compressive strength refers to the ability of a certain material or structural element to withstand loads that reduce the size of that material or structural element when applied A force is applied to the top and bottom of a test sample until the sample fractures or is deformed Materials such as concrete and rock are often evaluated using a compressive strength test and in these cases...

Aug 07 2010 0183 32 The desired concrete crushing failures shown in Figs 124 and 125 can only be achieved if IC CDC and PE debonding can be prevented from occurring before the design load to cause concrete crushing However this may not always be possible in which case it may be necessary to design for either IC or CDC debonding to occur at the design load so that concrete crushing will not...
