• Anchor bolts and base plates were detailed for tension and shear, ensuring stability under extreme load cases.

• Adequate embedment depth and edge clearances were maintained to prevent concrete failure.

• Soil capacity, settlement, and sliding resistance were verified to ensure long-term performance.

Design Outcome Summary

• The structural system provided robust lateral stability with efficient bracing and optimized load paths.

• Thermal movement allowances were successfully integrated, preventing overstress in piping and equipment connections.

• Connection detailing and anchorage design ensured reliable performance under cyclical and reversible loads.

• BIM integration improved coordination, eliminating clashes and streamlining fabrication and erection workflows.

This project involved the comprehensive structural design and detailing of a Conveyor System for a chemical production facility. The system comprised:

• Transfer Towers: 60-meter-high vertical structures housing equipment like bag filters, hoppers, and vertical conveyors.

• Conveyor Galleries: 32-meter-long steel spans carrying dual conveyors between towers.

• Trestles: Intermediate supports ensuring gallery alignment and structural continuity.

• Foundations: A hybrid system combining deep pile foundations and raft slabs to resist seismic forces, uplift, and dynamic loads.

The primary structural framework utilized fabricated box sections for columns and standard steel profiles for beams and bracing, optimized for torsional rigidity and load efficiency.

Engineering Challenges

• Wind Loads: High exposure due to tower height and open terrain.

• Seismic Effects: Located in a high seismic zone, requiring robust lateral load resistance.

• Dynamic Loads: Continuous conveyor operation imposed vibration and fatigue stresses.

• Thermal Expansion: Long galleries required movement accommodation.

• Elevation Coordination: Precise level matching at conveyor interfaces was essential for uninterrupted material flow.

Design & Detailing Strategy

1) Structural System

• Transfer Towers: Designed as braced frames with X-bracing for lateral stability.

• Conveyor Galleries: Engineered as truss systems to achieve long spans with minimal deflection and vibration.

2) Connection Engineering

• Pinned-Sliding Joints:

  • One end of each gallery was pinned to transfer vertical and lateral loads.

  • The opposite end featured sliding joints with bearing plates and guide assemblies to accommodate thermal expansion and dynamic movement.

• Welded Brackets to Tower Columns:

  • Custom steel brackets were welded directly to transfer tower columns to receive gallery support.

  • These brackets ensured direct load transfer and simplified erection.

3) Foundation System

• Pile Foundations:

  • Deep cylindrical piles anchored the towers and trestles, resisting uplift and seismic base shear.

  • They were appropriately used in areas with heavy vertical loads and limited space.

• Raft Foundations:

  • Reinforced raft slabs were also used at places where space restrictions were not stringent.

4) Platform Design & Equipment Integration

To ensure seamless installation and operation of vendor-supplied machinery, platform structures were designed with critical dimensional accuracy and layout precision:

• Anchor Point Coordination:

  • Platform beams and base plates were dimensioned to match vendor anchor bolt patterns and machinery footprints.

  • BIM models included embedded plate details and bolt layouts for fabrication and site verification.

• Access & Clearance Zones:

  • Layouts incorporated service access zones, maintenance walkways, and safety buffers around machinery.

  • Clearances were validated in BIM to avoid clashes with structural members, handrails, and adjacent equipment.

• Elevation Matching:

  • Platform heights were precisely aligned with conveyor discharge points and hopper inlets to ensure smooth material transfer.

  • Level control was maintained within tight tolerances to prevent vibration, misalignment, or flow disruption.

• Load Distribution:

  • Structural framing beneath platforms was designed to support concentrated equipment loads, with reinforcement at critical bearing points.

  • Load paths were optimized to transfer forces efficiently into the foundation system.

5) BIM Precision: Inclination & Elevation Coordination

• Conveyor galleries were modeled with exact slope geometry to support gravity-assisted material flow.

• Inclination was coordinated with mechanical discharge points and process equipment, ensuring optimal alignment.

Project Outcomes
