Malaysia　is　extensively　covered　by　residual　soils,　which　are　mostly　in　an　unsaturated　zone.　Determining　the　unsaturated　shear　strength　of　residual　soils　using　the　empirical　models　is　beneficial　because　of　the　limitations　of　experimental　methods.　Several　shear　strength　models　have　already　been　developed,　and　the　accuracy　of　some　of　these　models　has　been　examined.　However,　these　examinations　were　developed　based　only　on　the　particular　soils　initially　studied　and　may　not　be　applicable　to　Malaysian　residual　soils.　This　study　aims　to　provide　a　comparative　investigation　of　the　accuracy　of　some　of　the　published　shear　strength　models　for　unsaturated　soils　in　predicting　the　shear　strength　of　a　Malaysian　granitic　residual　soil.　The　published　shear　strength　results　of　the　soils　were　used　in　this　paper　to　provide　comparisons　between　the　predicted　and　measured　shear　strength　values　for　a　limited　suction　range.　Nine　various　equations　were　evaluated.　For　each　equation,　a　relationship　between　the　predicted　and　measured　shear　strength　data　was　generated.　The　linear　regression　line　with　zero　intercept　was　drawn,　and　the　slope　of　the　linear　regression　line　(SL)　and　coefficient　of　determination　(R2)　were　calculated.　This　study　showed　that　all　shear　strength　models　provide　relatively　acceptable　comparisons　between　measured　and　predicted　shear　strengths　by　a　maximum　of　10　%　difference　based　on　the　calculated　slopes　of　the　regression　lines.　However,　among　them,　three　equations　provided　more　accurate　predictions　in　comparison　with　the　others.　Copyright　©　2020　by　ASTM　International,　100　Barr　Harbor　Drive,　PO　Box　C700,　West　Conshohocken,　PA　19428-2959
