In add#l!on. load- dlrplaccment curve cm be apprornmarcd by ~veral straght lhncs wtth dlffcrent slopes The awend~ng curve has a slope that represents to the ruffncrr of the qeclmen before cracked. Wtlhxn a glven curve, the pre-craclung stage represented by the rlape of the rrcendtng curves a normally steeper than the desccndnng curve of the port-cracktng nrge. As expected. the ~t~ffncss of concrete plater were decreased after cncktng.

Rgumr 4.6 to 4.9 show that for pre-cracking stages. the slope of arcend!ngfurve of the btgpr nnfareemcnc ratto were al~ghtly htgher thvn thme fmm plates wlrh smaller re8nfommnt rauo.

All the figures lndicated that the plate stiffness lnfreacd with the lncrrorr of concrete-strength.
