Embodiment Construction
[0026] The present invention will be further described below in conjunction with accompanying drawing:
[0027] The present invention provides a novel box-shaped steel pier, such as figure 1 As shown, it includes a box-shaped steel pier body 100 , a diaphragm 200 , a buckling-resistant energy-dissipating frame 300 and a bottom plate 400 welded together sequentially from top to bottom.
[0028] The buckling-resistant energy-dissipating frame 300 has a hollow square structure that matches the shape of the box-shaped steel pier body 100, and the diaphragm 200 is a square plate whose size matches the cross-section of the box-shaped steel pier body 100. The steel pier body 100 and the anti-buckling energy-dissipating frame 300 are welded together through the diaphragm 200, and the transverse diaphragm 200 can ensure the smooth force transmission between the box-shaped steel pier body 100 and the anti-buckling energy-dissipating frame 300, forming an overall joint resistance.
