  30. INTRODUCTION • Structural Scope • Design Parameters • Gravity Framing • Seismic Framing • Four Alternatives • Material Selection • Systems • MEP

  31. 4 Alternates

  32. Alternate 1 Added Shear Wall

  33. Alternate 2

  34. Alternate 2 Added Bracing Tower

  35. Alternate 3 Added Support

  36. Alternate 4

  37. Alternate 4

  38. Alternate 4

  39. Seismic Framing for Each Alt. • Determine the magnitude of seismic forces • Design of Steel/Concrete/Composite diaphragm • Conceptualization of Lateral Force Resisting Elements • Details, Details, Details

  40. Seismic Loading

  41. Diaphragm • Distributes shear forces to LFRs • Static analysis showed maximum stresses to be 200 psi Maximum • Metal deck-PCC composite on 2nd,3rd,and Roof • Steel deck spans @ 10’ between beams “one-way” • Portland cement concrete via pump-truck • Wire mesh reinforcement and chord steel Shear Stud Reinforcement Steel Deck Concrete

  42. Overturning forces are not significant • LFR Systems • Steel • Chevron Bracing • Moment Frames • Concrete • Ductile Shear Walls • Moment Frame • Precast • Ductile Shear Walls • Post Tensioned Moment Frame

  43. Seismic Framing: CBF WT18x65 2L6x6x1/2 Shear Deformation

  44. Special PT Moment Resisting Frame Precast Sections: Moment Frame allowable in building code with special testing Construction Problems, Ductile and Safe, Allows long, open, uninterrupted spans PT Moment Frame

  45. Structural: Seismic Framing Shear Wall • Cast-in-Place • Simple • Ductility depends on failure mechanism • Requires Architectural Space

  46. Typical Connection Details Worst Case Steel Connections

  47. Typical Connection Details Column Foundation Column Beam Confinement

  48. Foundation System • Function of our foundation system • Handle vertical loads • Resist lateral forces • Site Profile • Bedrock • Very high bearing capacity • Very low settlements • Shallow Foundation • Bearing pressures 5 kips/sq.ft. • 4’x4’ Footings under columns • 12”-18” strip footing (Perimeter and LFRs)
