Research Abstract

The development of single tube type and tube-in-tube type with inner stiffening tube FLD member that are the key technologies of this study was carried out mainly by the full size tests. And the connection between RC frame and the latticed steel frame with FLD members was tested. Based on the results of this study, actual old RC building was reinforced and renewed very successfully. Main results obtained from the experiments, analysis and the renewal project are as follows ;
1) By using suitable length of end tubes with low yield points, considerable axial deformation and stable hysteresis loop were obtained. 2) DYNA 3D and NlKE 3D are successfully applicable for the simulation of the FLD members.
2) For obtaining larger plastic deformation and enough stable hysteresis loop, stiffeners inlayed into intermediate tube are very effective and the FLD member with stiffeners realizes the story-drift angle of 1/100-1/150 radian in assuming the ordinary RC buildings.
3) The tube-in-tube type FLD members with inner stiffening tube were tested and the design method was developed. Considerable cost-cut was realized in case of using FLD members in outdoor because of ease of surface treatment.
4) The design method of the connection between RC frame and the latticed steel frame was developed.
5) By the practical application of FLD members to the University building in order to reinforcing against earthquake, this system realized the epoch-making low cost/performance ratio because of short construction period and aesthetic appearance of the building facade.
