The research did to know effect of safety factor variation to deflection and momen on the plate and effect resistance of pole end. The method in use in counting equivalen subgrade modulus reaction (k?) that is Hardiyatmo Modification Method, where the value of variated safety factor (1,0; 2,0; 2,5; 3,0) and would be seen the effect if pole end resistance ignored (Qb=0) and if pole end resistance count (Qb?0). Deflection analisys using the finite element methode with the help of the computer program ?SAP2000 version 12?. The results deflections based on deflection of tolerance (??= 5 mm) Analisys result shows that on the use of safety factor 1,0 have smaller deflections than with other safety factors. Deflection analisys on poles for pole end resistance count (Qb?0) have smaller deflections based on deflection of tolerance (??= 5 mm). So on the desain Nailed-slab system more kind taking into account the resistance of the pole because the desain will be safer.} }
