Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically to an auxiliary structure of profiled steel sheet for damping H-beams. Background Technology

[0002] H-beams are an economical and efficient structural material with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They are named for their cross-section, which resembles the letter "H". Because all parts of an H-beam are arranged at right angles, it has advantages such as strong bending resistance in all directions, simple construction, cost savings, and light structural weight, and has been widely used.

[0003] The existing method for connecting H-beams is to first weld the H-beams onto a steel plate, and then fix the steel plate to a concrete base by anchoring. However, this method has poor seismic resistance and will cause cracks at the weld between the steel plate and the H-beam when exposed to vibration, which has an adverse effect on the fatigue and stability of the steel structure.
