Bay Final

Slide1: 

Final Presentation of Bay Engineer Yang, Yao-Hung Construction Manager David Walthall Architect Cindy Chan

Project Introduction: 

Project Introduction Engineer School of the Bay University in San Francisco 3-story building with a total of 30,000 sq. ft Provided innovative facilities with access to Internet and Telecommunication

Site Constrain: 

Site Constrain Earthquake Zone Humidity Control -Sea Fog Heating/Cooling Degree ( 1921/23 below 65 o F)

Architectural Constraint: 

Architectural Constraint 30’ height limit Maintain the existing footprint, circulation and transportation route

San Francisco State University: 

San Francisco State University

Spine Project: 

Spine Project Information Resource Center Act of Recording, Analyzing, and Storing located at the spine area

Curve Project: 

Curve Project The curve generates the movement physically, visually, and conceptually  

Slide8: 

CURVE Core +Steel MRF and lightweight concrete slab and steel deck SPINE Core + Brace+ Steel SMRF Structure Alternatives

Slide9: 

Structural Challenges Auditorium Cantilever Part Core wall Steel SMRF system Steel SMRF system Core wall Cantilever Auditorium

Slide10: 

Moment connection Steel SMRF W24 resist two NS-EW seismic force W24x229 I-Beam W24x131 I-Beam

Slide11: 

Core Wall Cast in place 10 inch core wall. Connect with gravity system C-shape core decreases torsion moment Share the vertical loading

Slide12: 

Cantilever Sap Modeling 10ft span Sap Modeling 20ft Moment Connection

Auditorium: 

Auditorium Add balcony to increase seats

Modeling Curve with SAP 2000 : 

Modeling Curve with SAP 2000

Foundation: 

– Water table - 16-20’ Soil Friction angle - 20 Cohesion - 250 lb/Ft2 Foundation Df square=4'  (Depth under the soil) Bsquare=3.6' (Width of the footing) Dthick=1' (thickness of the footing) 4X4 spread footing

Evaluation: 

Evaluation Pro A: Clear conceptual approach E: Uniform structural system C: Large amount of repetition, symmetry Con A: Exceeding height limit, form is too rigid E: Eccentric moment issue C: Large amount of glass structure Pro A: Multi spatial movement E: Simple gravity system C: Re-assembly of materials Con A: Lack of informal social space E: Complicated concrete beams C: Non-Uniform beam

Vision of the Engineering Building: 

Vision of the Engineering Building Encourage informal social interaction between faculty and student Ecological and Climate Responsive design to maximize building life cycle, increase user comfort and save energy cost

Projected Savings: 

Average Educational building consumes: 575.3 kWh/day 104 PV Panels generate 332.4 kWh/day At $0.12 per kWh, building saves $958.47 per day $349,839.86 per year Projected Savings

Slide35: 

Computer Integrated A/E/C Take advantage from web based technologies MSN NetMeeting Email Discussion Forums (PBL) Group web space (PBL)

Slide36: 

Group Assessment Collaborative Successes Strong integration of structure and architecture on design stage Friendly relationship Systematically achieve project requirement through interactive design process Collaborative Inadequacies Need to have more portions of product model shared Time Control

Slide37: 

Lessons learned Through sharing 3D models Save time and increases efficiency Easily to figure out and solve conflictions Everyone should use compatible technology Formatting correct communication protocols Understand what other discipline needs Properly propose what you need Take necessary courses needed
