碩士 === 國立中央大學 === 土木工程研究所 === 83 === This research is to investigate the distinct characters of t- he crack width and the cleavage length between the high strength conccrete and the common strength concrete.The four factors,i.e. compressive strength,level of steel stress,bar diameter and cov- er thickness are considered in the experiment, which get a few conclusions as following: The concrete surface crack width of the HSC is smaller than the MSC,LSC. But the cleavage length at the steel concrete int- erface under loading of the HSC is grater than it of the MSC,L- SC.So,the allowable crack width design method of the Code has t- he non- conservative tendency. From the experiment datas of 216 uniaxial tension specimens get some results : The cleavage length at steel concrete inter- face under loading of the HSC is greater than it of the MSC,and LSC. The concrete surface crack width under loading of the LSC is greater than it of the MSC,and HSC.The concrete surface crack wdth under unloading of the MSC is greater than it of LSC and HSC .
