Uniaxial Kent-Scott-Park concrete model with linear unloading/reloading according to the work of Karsan-Jirsa and no strength in tension. The model contains a compressive strength of fpc, a strain at the compressive strength of epsc0, a crushing strength of fpcu, and a strain at the crushing strength of epscu. Compressive concrete parameters should be input as negative numeric values for this model to behave properly. Specification of minimum and maximum failure strains through the -min and -max switches is optional. The argument matTag is used to uniquely identify the material object among material objects in the BasicBuilder object. More...
