How is Bamboo Construction???

How can we construct bamboos???

How is the original Bamboo Construction???

Substitutive:bambooto replace other possible material with bamboo, thus bamboo will be constructed to fit with other type of construction. established structure

Substitutive:Laminated Bambooestablished structure from timber laminated bamboo

established structure from steel bamboo split truss Substitutive:Split Construction

established steel reinforced concrete bamboo reinforced concrete Substitutive:Bamboo Reinforced Concrete

established space structure from metal bamboo space frame mostly three dimensional frameavoid eccentricity in force transferpoles under tension or compressionusing steel connector Substitutive:Poles Construction

Conventional:bambooa set of unwritten rules, a set of agreed, stipulated or generally accepted standards, norms or criteria. the construction that come from the specific character of bamboo Convention:bamboo construction

Conventional Bamboo Construction:Traditional or VernacularModernized or Engineered Conventionalstructures made by empirical buildersfurther development using scientific approach

Conventional: Traditional/ VernacularBamboo Poles Constructionmostly consist of planar frames (two dimensional frame)mostly in one layer bamboo poles under compressive or bending stressespresent of eccentricity in force transferusing fish-mouth, rope, plug-in, and positive-fitting connection

Conventional: Traditional/ VernacularBamboo Splits/Woven ConstructionPlastered Bamboo Constructionrelatively simple form plastered/ rendered with mud, lime or cow dung

Conventional: Modernized/ EngineeredBamboo Poles Constructiontwo or three dimensional frames mostly in more than one layer poles under compressive or bending stressespresent of eccentricity in force transferusing nut-bolts connector and fish-mouth connection

Conventional: Modernized/ EngineeredBamboo Splits/Woven Constructionrelatively complicated formmostly in experimental building Plastered Bamboo Constructionplastered/ rendered with mortarwith or without additional chicken wirecombined with poles structure
