Design aspects of steel I-girders with corrugated steel webs
Corrugated web girders represent a new structural system emerged in the past two decades. The girder’s flanges provide the flexural strength of the girder with no contribution from the corrugated web which provides the girder’s shear capacity. Failure of the web occurs by steel yielding, web buckling or interactively between them. Lateral torsion and local flange buckling of corrugated web gird...
متن کاملDesign of an Ultrasonic Steel Horn with a Bézier Profile
A novel ultrasonic steel horn with a Bézier profile is developed. The first longitudinal displacement mode of the horn is exploited for high displacement amplification. An optimization scheme and finite element analyses are used to design the horn. The displacement amplification and stress distribution characteristics of the Bézier horn and catenoidal horn are examined. Prototypes of the horns ...
متن کاملBistable Dynamics of Turbulence Spreading in a Corrugated Temperature Profile
We present a new model of turbulence spreading in magnetically confined plasma. A basic question in turbulence spreading is how to sustain finite amplitude fluctuations in a stable subcritical region, where linear dissipation of the turbulence is strong? The answer to this question relies on a consistent treatment of mesoscale temperature profile corrugation and microscale turbulence. We argue ...
متن کاملAn Experimental Study on the Shear Hysteresis and Energy Dissipation of the Steel Frame with a Trapezoidal-Corrugated Steel Plate
The steel frame reinforced with steel shear wall is a lateral load resisting system and has higher strength and shear performance than the concrete shear wall system. Especially, using corrugated steel plates in these shear wall systems improves out-of-plane stiffness and flexibility in the deformation along the corrugation. In this paper, a cyclic loading test of this steel frame reinforced wi...
متن کاملThe Stress-related Damping Ratio of Box Girder with Corrugated Steel Webs
In this paper, the stress-related damping ratio formula of box girder with corrugated steel webs is introduced. Using response spectrum method, an iterative algorithm is proposed to calculate the seismic response and the stressrelated damping ratio under different seismic intensities. Based on a simply supported composite box girder bridge with corrugated steel webs, the stress-related damping ...
