Introduction
Reinforced concrete design errors surface late on industrial and building projects: undersized footings, cracked containment walls, resonating compressor blocks and congested reinforcement that cannot be placed on site. This Core Concept course takes structural and civil engineers from materials, durability and limit state design under ACI 318 and Eurocode 2 through beams, slabs, columns, shear and torsion, then into foundations, equipment foundations, pipe racks, retaining walls and detailing. Participants produce an Industrial Structure Design Calculation Package for an element set drawn from a plant or building project.
Course Objectives
- Select concrete cover, exposure class and mix requirements that protect reinforcement against carbonation and chloride attack
- Derive factored load combinations and design beams, one-way and two-way slabs, columns and flat slab punching zones to ultimate and serviceability limit states
- Design shear and torsion reinforcement and check crack widths and long-term deflection for members under sustained load
- Size and reinforce isolated, combined, mat and piled foundations and check block foundations for rotating equipment against resonance
- Design concrete pipe racks, retaining walls and liquid-retaining structures and prepare reinforcement drawings and bar bending schedules
- Assemble and defend a design calculation package for an industrial structure element set, including software output validation
Target Audience
- Engineers who carry out structural calculations for plant, utility and building projects
- Design engineers in engineering, procurement and construction teams who size foundations, pipe racks and equipment supports
- Checking engineers who review and approve calculation packages and reinforcement drawings
- Plant civil engineers who assess existing concrete structures and specify repairs
- Detailers and drafting leads who convert design output into reinforcement drawings and schedules

- Move beyond member design in week two to foundations, vibrating equipment supports, pipe racks and containment walls
- Catch congested reinforcement, weak anchorage and resonance risks before drawings reach site
- Compare design practice with engineers from oil and gas, power, water, manufacturing and commercial building projects
Conclusion
Concrete structures in plants and buildings perform when durability, strength, serviceability and constructability are designed together. Week one covers materials, loads, limit state principles, beams, slabs, columns, shear, torsion and serviceability, closing with a guided building frame case. Week two applies that base to foundations, equipment foundations under dynamic loads, pipe racks, retaining and containment structures, detailing, software validation and repair. Participants leave with an Industrial Structure Design Calculation Package ready for checking on their next project.
