Study Notes
Bamboo in Construction
- Bamboo is a lightweight, versatile, and renewable construction material
- Projected to use new construction methods
- Growing demand worldwide but lacks design standards
- Unique circular hollow cross-section and internal nodal support of bamboo
- Curvature of bamboo members for stress distribution needed
- More environmentally sustainable than timber but less orthotropic
- More out-of-plane stiffness than timber
Bamboo Material Properties and Failure Mechanisms
- Renewable and sustainable material, similar to timber and cost-effective
- Increased interest due to sustainability
- Fast growing and renewable with strong structural properties
- Material not commonly used due to non-homogenous cross-section and irregularities
- Many factors impacting structural properties (climate, topography, soil, altitude, cutting, treatment, age, stem and humidity)
- Variance of bamboo properties creates uncertainty
Design of Grid Shells
- Bamboo grid shells formed basis for structural analysis and design
- Grid shell composed of individual members
- Light and strong, curved form-active structure
- Reduces frameworks cost and complexity of alternative shell structures
- Thin glass cladding material between bamboo members is used
- Creates waterproof shelter, natural ventilation, and overcomes inconsistencies
Connection Type
- Connections in bamboo grid shells prevent sliding/torquing of members, enabling a fixed joint
- Allows transfer of forces between members
- Crossing of members provides inherent lateral support system, distributing loads more effectively
- Round hollow section prevents similar joints as wooden structures
- Binding and bolted connections are optional solutions
Structural Design - Preliminary Curved Bamboo Member Design Guidelines
- Method uses finite element analysis
Parametric Design
- Parametric design describes key structural parameters
- Parameters varied to get optimal solution
- Computational techniques used for optimal solution
- Used for complex architectural geometry; also used for structures
Case Study - Structural System Design
- Three design case studies with plan, front elevation, and side elevation figures
- Dimensions provided per design (e.g., 6.6m, 6m, 3.45m)
Proposed Research Method
- AutoCad and Strand7 software use for preliminary modeling
- Material and property assignment
- Local and global analysis, including multiple load cases
- Includes SLS and ULS design categories
- Analyses of effects of changing section properties, thickness, diameter
- Preliminary modeling, material and property assignment is done in the first step
- This is followed by local and global analysis with multiple designs and different loading conditions
- This includes an investigation of the effect of changing structural parameters
Model Analysis (Models 1, 2, and 3)
- Figures with labeled displacements and stresses (e.g., Max Displacement = - 5.89 mm, Max Tension = 0.12 MPa)
- Load cases and figures representing the results of this analysis
Durable and Environmentally Friendly
- Bamboo is durable and environmentally friendly
- Minimal waste production
References (Note: Not all are complete as the page content is incomplete)
- List of various research papers and articles related to bamboo construction
- Authors and publication details for these articles
- Include keywords like "carbon dioxide emissions", "sustainability", "structural material", "environmental design", etc. from the references provided
