The tower is connected to the podium by a steel corridor with a span of 40m on the 4th floor.
The corridor is an office area on the ground floor and a roof garden on the top floor. The whole structure is in the form of steel truss, which is suitable for large-span structure because of its large load bearing capacity and small deformation.
And through the 8 finished seismic bearings and the main structure to form a flexible connection between the two ends of the truss using “X-shaped” cross web, so that the floor and roof bearings evenly share the vertical load of the corridor, the trusses are connected to the main structure by the “X-shaped” cross web.
The truss ends, which have high internal forces, are also strengthened.
The finished bearing adopts lead core rubber bearing, the rubber can release the horizontal deformation of the bearing, and the lead core can restore the bearing to its original position through its elastic recovery ability.
The support is connected to the pre-embedded parts at the top of the bull’s leg, and the bull’s leg and the connected frame columns have built-in steel profiles to improve the bearing capacity and safety reserve of the bull’s leg.
Such a steel structure corridor, each square contains 300 kilograms of steel, then how much is the cost?
