| Abstract: | The optimal design of Portal frames was made by adjusting the combined vaiables of column space,spans and loads,on the basis of which the method of choosing the variables was determined. Thus the different quantities of steel use were given with different spans and bays and an example of the contrast of steel use was given with different spans of Q235 and Q345 portal frame.By optimal design,the reasonable constructral design,safety and economic effectiveness can be statisfied. |
