摘要：

In　this　paper,　the　base　force　element　method　(BFEM)　on　damage　mechanics　is　used　to　analyze　the　fracture　properties　of　recycled　aggregate　concrete　(RAC)　on　meso-level.　The　recycled　aggregate　concrete　is　taken　as　five-phase　composites　consisting　of　natural　coarse　aggregate,　new　mortar,　new　interfacial　transition　zone(ITZ),　old　mortar　and　old　ITZ　on　meso-level.　The　random　aggregate　model　is　used　to　simulate　the　meso-structure　of　recycled　aggregate　concrete.　The　size　effects　of　mechanics　properties　of　RAC　under　uniaxial　tension　loading　are　simulated　using　the　BFEM　on　damage　mechanics.　The　simulation　results　agree　with　the　test　results.　This　analysis　method　is　the　new　way　for　investigating　fracture　mechanism　and　numerical　simulation　of　mechanical　properties　for　recycled　aggregate　concrete.
