A new method for problem of hyper-static axial force computation

  • Axial force diagram for general frame can be obtained from bending-moment diagram and shear force diagram,but some axial forces can not be obtained from using the shear force diagram directly when axial force was hyper-static.Through analysising the structural features,putting forward to a new method,the method combines the characteristic of which only the pillar exists axial force when axial concentrated force acts on the pillar's joint with mechanical means.Example shows the method has spontaneous and convenient to computing. Key words: hyper-static frame; axial force; computational method.
