  1. THE BUILDING ENVELOPE: Lecture 5 Analysis of Wind Loads: ASCE 7-02 Method 1: Simplified ASCE 7-02 Method 2: Analytical ASCE 7-02 Method 3: Wind Tunnel

  2. ASCE 7-02 METHOD 1: LOW-RISE BUILDING

  3. ASCE 7-02 METHOD 1: LOW-RISE BUILDING

  4. 160 ft 200 ft 100 ft ASCE 7-02 METHOD 2: OFFICE BUILDING Determine design pressures for windows on a 16-story office building near Houston, Texas

  5. ASCE 7-02 METHOD 2: OFFICE BUILDING Building Conditions: • Topography: Flat • Terrain: Open; no gravel roofs with 1500 ft • Height: 160 ft • Classification: Category II • Openings Windows, 10 sq ft in area • Velocity 120 mph

  6. ASCE 7-02 METHOD 2: OFFICE BUILDING Factors affecting wind pressure: Kz = terrain factor at elevation z Kzt = topography factor = 1.0 Kd = directionality factor = 0.85 V = design wind velocity = 120 mph I = importance factor = 1.0 G = gust effects C = building geometry

  7. ASCE 7-02 METHOD 2: OFFICE BUILDING

  8. ASCE 7-02 METHOD 2: OFFICE BUILDING

  9. ASCE 7-02 METHOD 2: OFFICE BUILDING

  10. ASCE 7-02 METHOD 2: OFFICE BUILDING

  11. ASCE 7-02 METHOD 3: OFFICE BUILDING Leighton Cochran will provide a illustration of design wind speeds for cladding derived from wind tunnel studies
