Experimental study on simply supported slab of reinforced concrete stiffening ribbed hollow pipe girderless floor;

Influences of rib stiffeners on hysteretic behavior of end-plate connections;

L-joints without rib stiffener are semi-rigid connections.

Among them, four end plates are reinforced with rib stiffeners, which are in alignment with beam webs, and constant axial compression force is applied at the end of seven columns during the test.

Static behavior analysis of top and seat angle with stiffener connection beam-to-column joints;

The stiffeners that were mounted in compression zone can decrea.

FEA models were established to make analysis on the influence of wall panel,horizontal rib stiffener and inside steadying bar to mechanics properties of one typical flue gas duct in fuel electric plant.

During the analysis, two parameter was considered:the depth and length of stiffening rib.

The paper analyses the stability of rib slab on method of energy,the formula of longitudinal critical force is deduced,and rational arrangement of stiffening rib is discussed.

The steel silo wall is a typical cylindrical shell structure which is very sensitive to the boundary conditions, so setting up stiffening rib on the silo wall can improve the stability effectively, but it is the lack of related research.

The codes and specifications of China in steel-structure field require that the bearing ability of shear force in panel zone must be sufficient and the inclined stiffener should be applied.

The codes and the specifications in steel-structure field in China,such as GB50017-2003 , JGJ 99-98 and CECS 102:2002, said the bearing ability of shear force in panel zone must be sufficient, otherwise the inclined stiffener should be applied.
