Meanwhile , according to the reduced theoretic of the open - web truss , the strength simplification computational method are proposed , and in comparison of the theoretical calculating value with the tested one and the behavior analysis of the tested beams during the process , the hypothesis and the theory of the beam are verified and the stress distribution of the circular hole castellated beam is also obtained 通过费氏空腹桁架简化计算理论值与实测值的对比分析以及对试验梁在试验过程中的性态分析，验证了理论计算及各项假设的正确性，分析得出圆孔蜂窝梁圆孔周边应力分布特征；并通过挠度分析，提出了实用的简化计算式。
Many optimization joints mid design methods which have been applied in actual engineerings are put forward , including the rc looped - beam joint , enforced - steel loop joint , joint between columns filled with steel tubes and rc beams , joint between columns filled with steel reinforced concrete and rc columns , joint between column filled with steel tube and composite beam , composite beam design method , prestressed laminated open - web truss mid so on 其中，提出的较优化的钢筋砼环梁节点、钢加强环节点、钢管砼柱与钢筋砼柱节点、钢骨砼柱与钢筋砼梁节点、钢骨砖柱与组合梁节点及组合梁设计方法、预应力叠层空腹桁架等，都已应用于实际高层建筑中。
