Abstract: Failures of strand–concrete bonds have been widely observed in load tests of precast-pretensioned concrete I girders. Through a review of 22 test programs, 15 terminologies were identified to describe failures associated ...

Abstract: Residential shelter performance, in the aftermath of the devastating May 20, 2013, EF5 tornado that struck Moore, Oklahoma, was investigated by a reconnaissance team comprised of researchers from several universities. The ...

Abstract: Transfer length is a significant parameter in the design of pretensioned concrete members. The estimation of transfer length is typically achieved by measuring concrete strain or strand slip at the member ends. The end ...

Abstract: This paper presents an experimental research work to determine temperature gradients in concrete bridge girders under natural environmental conditions. Three AASHTO Type I-girders having different configurations (with and ...

Abstract: Several modes of bridge distress related to interactions with approach roadways have been observed in Oklahoma through routine maintenance inspections. Upon closer review it was found out that there are two main mechanisms ...

Abstract: Thermally induced stresses can build up in rigid pavements without pressure relief joints. The pressure created becomes a problem for adjacent structures such as bridges. The pressure can cause the pavement to push on the ...
