Analysis and prediction of ultimate strength of high-strength SFRC plates under in-plane and transverse loads

Plates are most widely used in the hulls of floating concrete structures, bridge decks, walls of offshore structures and liquid storage tanks. A method of analysis is presented for the determination of loaddeflection response and ultimate strength of high-strength steel fiber reinforced concrete (HSSFRC) plates simply supported on all four edges and subjected to combined action of external compressive in-plane and transverse loads. The behavior of HSSFRC plate specimens subjected to combined uniaxial in-plane and transverse loads was investigated. The proposed analytical method is compared to the physical test results, and shows good agreement. To predict the constitutive behavior of HSSFRC in compression, a nondimensional characteristic equation was proposed and found to give reasonable accuracy.
