Process for designing a square reinforced concrete column following ACI-318 codes

In this construction video, you will be familiar with the detailed process for creating design of a square reinforced concrete tie column by adhering to ACI codes.

The video focuses on ACI-318 requirements for columns. ACI-318 comprises of the materials, design, and construction of structural concrete essential for buildings and where relevant for non-building Structures. The Code also highlights the strength evaluation of prevailing concrete structures.

In ACI 318 is available in printed and digital formats and can be accessed on desktop, tablet, and mobile gadgets. It is obtainable in Spanish, Chinese, and Korean.

Various topics are included which range from drawings and specifications; inspection; materials; durability requirements; concrete quality, mixing, and placing; formwork; embedded pipes and construction joints; reinforcement details; analysis and design; strength and serviceability; flexural and axial loads; shear and torsion; development and splices of reinforcement; slab systems; walls; footings; precast concrete; composite flexural members; prestressed concrete; shells and folded plate members; strength evaluation of existing structures; special provisions for seismic design; structural plain concrete; an alternate design method in Appendix A; unified design provisions in Appendix B; and alternative load and strength reduction factors in Appendix C.
