| Abstract: | From micro level,concrete is
regarded as a two-phase heterogeneous composite consisting of coarse aggregate and
hardening cement mortar matrix.The Rigid Body Spring Model (RBSM) that is fit to solve
limit load and deal with microcracks is adopted.The effects of different components on the
material parameters are studied.The relationship between micro structure and macro
behavior is studied. |
