Bending Fatigue Test on Welded Joint between Vertical Stiffener and Deck Plate

Kentaro YAMADA, Tomotaka OSONOE, Tatsuya OJIO

pp. 1-8

DOI:

10.11273/jssc1994.14.55_1

Abstract

Fatigue tests in plate bending type were carried out for orthotropic steel deck plate with fillet welded vertical stiffener. Such detail is prone to fatigue cracks when it is subjected towheel loads in service. Fatigue crack initiates and propagates from fillet weld toe, and propagates around the end weld. Then, fatigue crack propagate to deck plate perpendicular to applied stress ranges. Fatigue life increased by drilling hole of 100mm diameter to reduce stress concentration at vertical stiffener ends, or by grinding fillet weld toe.

Simulation of Progressive Failure of Perimeter Columns in Framed-Tube Structures

Hiroyuki Tagawa, Rei Okada, Shinya Sumitani, Satoshi Yamada, Akira Wada

pp. 21-28

DOI:

10.11273/jssc1994.14.55_21

Abstract

The framed-tube structure consists of rigid moment frames in the perimeters and floors which provide lateral support to prevent perimeter column buckling. When perimeter columns deform toward the outside of the structure, simple connections between floors and perimeter columns may rupture in tension. This behavior is simulated by the monotonic quasi-static compression tests for steel column laterally supported by aluminum board with a notch. Major findings include: (1) even 1 % lateral support strength provide satisfactory behavior of the column up to yield strength, (2) as the number of lateral supports increases, column axial deformation at the rupture of lateral supports increases, (3) as the lateral support strength increases, the degradation of the column after the peak strength becomes smaller.

Study on The Statical Characteristics of WF Beam-to-SHS Column Connections Using Paddle Bolts

Shunji FUJII, Hiroshi MASUDA, Atsuo TANAKA

pp. 29-35

DOI:

10.11273/jssc1994.14.55_29

Abstract

In this experimental study, the statical characteristics of WF beam-to-SHS column connections using special shaped high strength bolts called "Paddle Bolt" was investigated. Because the method of construction does not use welding for connection, execution efficiency is better than a through diaphragm type. Bending out of plane of column flange in connection influences elastic stiffness of connection. Tested it with cruciform specimens based on conventional findings, and was aimed for practical use of connection. From the results of this test, flexural strength of connection was able to be almost evaluated with prediction formula by a yield line theory.

Study on Approximate Technique Taking Deflection of Foundation Girders and Pile-Soil into Consideration for Structural Analysis

Kenji MIYAUCHI, Motohiko YAMADA

pp. 37-46

DOI:

10.11273/jssc1994.14.55_37

Abstract

The purpose of present study is to propose the approximate technique taking deflection of foundation girders and pile-soil into consideration for structural analysis. Separation of the upper structure from the pile-soil structure is the practical method in case of structural frames with foundation girders constructed from reinforced concrete of high stiff ness, but it isn't a general method in case of foundation girders of finite rigidity. In the pres ent analysis, two approximations are applied, and those enable to separate the analysis of the upper structure from that of the pile-soil structure. This is proposed as a new approximation method of rotation-rigidity.

FATIGUE IMPROVEMENT METHOD FOR WELD REPAIRED CRANE RUNWAY GIRDER BY ULTRASONIC IMPACT TREAMENT

Tominaga TOMONORI, Kazumi Matsuoka, Yoshiaki SATOH

pp. 47-58

DOI:

10.11273/jssc1994.14.55_47

Abstract

A fatigue improvement method using ultrasonic impact treatment, which improves both toe profile and residual stress condition, was examined. This method is applied to in-plane-gusset detail and out-of-plane gusset detail of existing crane runway girders. Comparison with conventional grinding method was conducted by small joint specimen fatigue tests, and UIT gave much better result. Also, its applicability to mild steel and influence from repair weld is examined through girder fatigue tests. Significant fatigue improvement was obtained for 400MPa class mild steel. Also, the effect is not reduced by repair weld. This result has encouraged the proper application of UIT for existing CRGs.

Elasto-Plastic Behavior of Circular-Column-to-H-Beam Connections employing 1000N/mm2-Class Super-High-Strength Steel

Naoki TANAKA, Takashi KANEKO, Hiroyuki TAKENAKA, Satoshi SASAKI

pp. 59-72

DOI:

10.11273/jssc1994.14.55_59

Abstract

Super-high-strength steel with yield points of 800-1000N/mm2 is about to be used for building frames. A design method needs to be established that takes into account the poor welding performance as well as the larger elasticity of these materials. To this end, cruciform circular-column-to-beam connection specimens were tested and analyzed. Frame connection can be made by partial butt welding or super-high-strength bolts using an ordinal outer or ring diaphragm, and a horizontal beam haunch. Tests and analytical results confirmed that the elastic region extends further than that of a frame made of ordinary steel by about 1 % of story deflection angle. Initial stiffness, yield strength and maximum strength due to local beam buckling can be assessed by ordinary calculation methods. However, the slip and fracture strength of bolt joints using super-high-strength steel and bolts needs her investigation.

DOI:

10.11273/jssc1994.14.55_73

Abstract

Structural system using buckling-restrained knee brace dampers was proposed in order to stabilize the construction quality of low and middle-rise buildings. In this paper, we look into the possibility of this structural system for highrise buildings. We designed high-rise frames using this system, and carried out earthquake response analysis of them. Adding this, we considered the method to decrease the earthquake response of them.

Response Behavior of Steel Latticed Cylindrical Shell Structures with Hysteresis Dampers in the Substructure

Seishi YAMADA, Eiji SAITO, Yukihiro MATSUMOTO

pp. 87-97

DOI:

10.11273/jssc1994.14.55_87

Abstract

For the design of shell-like space frames located in seismic area, it is very important to give considerable attention to the dynamic behavior and to make clear how to reduce the seismic response. For the difficult dynamic problem of single layer latticed cylindrical roof structures, this study has previously analyzed their fundamental earthquake response behavior using the finite element method, and showed the relationship between the strain energy and the various response quantities in detail. This paper shows the earthquake response behavior of those with hysteresis dampers in the substructure and suggests the usefulness of this new structural control system.

Effect of Column-to-Beam Strength Ratio on Maximum Story Drift Angle Response of Steel Frames under Horizontal Bi-directional Ground Motions

Ryoma KIMURA, Koji OGAWA

pp. 111-121

DOI:

10.11273/jssc1994.14.55_111

Abstract

This paper presents the effect of column-to-beam strength ratio on the maximum story drift angles of steel frames subjected to bi-directional ground motions. Analyses were carried out using bi-directional ground motions as directions of a strong axis and a weak axis. Followings were deduced; Maximum value of story drift angles given out of calculated results in arbitrary directions can be almost approximated by maximum story drift angles obtained responses when ground motion of strong axis is applied in the direction of parallel to the structural plane or in the direction of a half of right angle to it in cases where column-to-beam strength ratio is over√2.

Fatigue Strength of Steel-Concrete Composite Slab using Angle Shape Shear Connector

Kazuo TATEISHI, Sung-Min CHOI, Daisuke UCHIDA, Koichi ASANO, Kiyoshi KOBAYASHI

pp. 123-132

DOI:

10.11273/jssc1994.14.55_123

Abstract

Fatigue strength of welded joint between angle-shape shear connector and bottom plate in steel-concrete composite slab was investigated by fatigue tests. Local stress around the welded joint was also investigated by FEA. In fatigue tests, fatigue cracks initiated and propagated at the welded toe. The fatigue cracks were caused by stress concentration at the welded joints due to the local bending deformation of bottom plate. This local bending deformation was observed when the bond between concrete and steel plate was lost, and analytically simulated by FEA carried out on slab members in practice. After these investigations, it was confirmed the stress level at the welded joint was small and much less than the fatigue limit even when the desiun truck loads were atinlied.
