2.7 Connections Design
All composite column to RCC Slab/ RCC footing has been analysed to transfer the axial load through bearing of steel plate on slab or footing. For slab connection
300x300x20mm plate has been used.
Appendix B for base plate design. Both manual and FE calculations have been provided.to column connection, the tubular of composite column has been embedded into concrete column
and embedment length has been calculated
