Abstract：The reinforced concrete structure is widely used in the constructional engineering .Due to the toughness and flexible characteristics , the steel bar cannot be taken over by other materials , and plays important role in architectural structure .With the expansion of architectural scale , the steel bar has become the key com-ponent in architectural structure , and promotes its development in depth , height and breadth .Because the steel bar has high prize in unit volume , and followed with large usage , its cost has become the key point in cost con-trol during management process , which also is an important factor to decide whether a project could gain some profit .The problem in steel bar cutting not only affects the quality of constructional engineering , but also decides working process .The excessive consumption of steel bar could lead to a waste , and makes the cost much higher . Hence, it is necessary to optimize the problem in steel bar cutting , which can effectively avoid the waste , lower the cost and get a higher profit .In this paper , we have done some studies on steel bar cutting , constructed the linear and no-linear programming models , and seek the optimal scheme by utilizing the software of LINDO and LINGO.The optimal scheme gotten from mathematical programming model show that our model could effectively improves the utilization ratio of steel bar and control over the engineering cost .
