AI Technical Summary
Traditional slab-column connection nodes have complex structures, numerous components, difficult concrete pouring, and huge column caps with poor punching shear resistance, which cannot meet the requirements of vertical evacuation structures for shear resistance and seismic performance.
The connection node between reinforced concrete slab and concrete-tube steel column is adopted. By welding flanges to the ends of the concrete-tube steel column and connecting them with prestressed bolts, the construction process is simplified, the critical shear perimeter is enhanced, the development of shear cracks is limited, the number of concrete pouring steps is reduced, and the seismic performance is improved.
With its reasonable structure, convenient construction, and clear force transmission path, it improves the shear resistance and ductility of the slab-column structure, enhances its seismic performance and resistance to progressive collapse, and simplifies the construction process.
