VERIFICATION OF SHEAR TRANSFER MECHANISM BASED ON CONTACT THEORY : Study on shear transfer mechanism on concrete crack surface Part 1

Abstract

In the previous paper， the authors proposed thenew shear loading systcm in order to eva 訌 uate shear transfer mechanism en concrete crack sur 飴 ce ． The overview ofthis testing system was explained already ． ln this paper， the sbear transfer mechanism is verified ffOm experirnental resultS conducted using th 正 s new device ， Furthermore ， the experiments with constant contact ratio is conducted to observe thc behavior of contact stress on local crack surface ． As a r ¢ sult ， the behaVior ofeontact strcss can be ebtained for the first time ． And iI was con 婿 ed that softening phenomenon was occurred on bcal crack surface ． KCV レords ： Concrete Craek Surfaee， C 厂ack width ． Sh 砌 7 肋 η K Co η' σo ！5舵 5畠 Constitutive Eguation
