| Abstract: | Based on the material character of BFRP rebar and the plastic method for concrete structure,the concept on nominal yield strength of BFRP rebar was proposed,the yield condition of concrete and BFRP rebar were determined,and the failure mechanics of two-way BFRP rebar reinforced concrete slabs under central concentrated load was established.The calculating expression on plastic solution of ultimate punching capacity for two-way BFRP rebar reinforced concrete slabs under central concentrated load was educed using the virtual work principle. |
