Structural Analysis

• 4-storey reinforced concrete apartment building
  

  

  What?

  • Design and provide calculation packs on the main gravity members, slab reinforcing steel & seismic force resisting system
  • Provide detailed mark-ups of designs for drafting team

  How?

  • Derived loads from hand calculation and used Excel to create critical load case combination table
  • Designed beams, columns, and flat plates using hand calculations, spColumn and spSlab
  • Performed a linear dynamic analysis using ETABS in accordance with NBCC-2015 to obtain lateral seismic forces and designed the shear walls in S-CONCRETE, as moderately ductile according to A23.3-14
• Demolition and Reconstruction of a Parking Garage Slab
  

  

  What?

  • Complete demolition and reconstruction of the parking garage structural slab
  • Analyse the new reinforced concrete slab and design of the reinforcing steel

  How?

  • Specified the structural sections and details for temporary column supports during demolition
  • Conducting analysis using spSlab and SAFE and designing the reinforcing steel
• Structural Steel Frame Vertical Addition
  

  

  What?

  • The new steel frame to wrap around the existing building at the second floor before continuing above it
  • Analysis and design of all structural steel columns, beams, joists, cold formed decks, diaphragms and moment frames
  • Coordinated the structure with the intricate architectural layout

  How?

  • Participated in coordination meetings with a team of architects, structural engineers, mechanical engineers and general contractors to realize client requirements while ensuring structural feasibility
  • Used ETABS to design gravity members & seismic moment frames according to S16-14
• Structural Steel Aircraft Hangar
  

  

  What?

  • Analysis and design of all structural steel columns, beams, box trusses, cold formed decks, diaphragm and concentric cross-braced frames
  • Meticulous design accounted for torsion caused by the eccentricity between the center of mass and center of rigidity. The offset was due to the absence of bracing bents on the mega-door side of the structure

  How?

  • Derived loads from hand calculation and used Excel to iterate for the center of rigidity and to transfer the torsional moment to the three remaining cross-braced sides of the structure
  • Utilized a SAP2000 3D model to design wind columns, box trusses and verify the chosen lateral sections from hand calculation
• Portal Frame Building With Overhead Crane
  

  

  What?

  • Design and provide calculation on the main portal frame members, purlins and bracing
  • Provide detailed markups of designs for drafting team

  How?

  • Used SAP2000 to output design actions
  • Documented design iteration process in Bluebeam
