A　new　method,　meso-element　equivalent　model,　was　proposed　in　the　paper　to　analyze　the　macro　mechanical　properties　of　concrete　materials.　The　method　was　described　to　start　with　the　meso-scale　of　concrete;　the　Monte　Carlo　method　was　used　to　generate　the　random　aggregate　model　of　concrete　composed　of　the　aggregate　particles　and　the　mortar　matrix.　And　then,　the　finite　element　grid　was　meshed　based　on　characteristic　element　scale　of　concrete　materials,　and　the　mesh　grid　was　projected　onto　the　established　random　aggregate　model.　The　mechanical　properties　of　every　element　were　determined　by　equivalence　method　of　composite-materials.　The　proposed　approach　reflected　the　recognition　of　the　macro-scopic　mechanical　properties　of　material　nonlinearity　due　to　their　inherent　heterogeneity.　While　the　meso　mesh　whether　affecting　the　macroscopic　mechanical　properties　of　concrete,　was　taken　as　the　criterion　for　the　non-uniformity　description.　Hence,　comparing　with　the　meso-mechanical　method,　the　excellent　advantages　of　the　method　was　that　the　system　reduced　the　number　of　degrees　of　freedom　greatly,　which　improved　the　computational　efficiency,　especially　for　3D　problems.　The　examples　analysis　in　the　paper　confirmed　the　high　efficiency　of　this　method.
