Incremental Dynamic Analysis of a Five-Story Laminated Guadua Bamboo Framed Building


Abstract eng:
The increasing interest in finding renewable materials for construction purposes has led to consider bamboo as an important alternative to wood and wood–based products, since it has a fast growing rate and high strength–to–weight ratio, besides outstanding environmental advantages. Furthermore, laminated bamboo products have emerged as a solution to the inherent difficulties of constructing with round pole bamboo. This study presents a preliminary evaluation of the seismic performance of a five–story laminated bamboo frame building, by means of an Incremental Dynamic Analysis (IDA). The building archetype is based on typical construction practice in Colombia for low– and mid–rise residential buildings, while the structural system is based on a light–framed shear wall system similar to conventional wood construction practice. Vertical and horizontal diaphragms are comprised of laminated sheathing panels made from Guadua angustifolia Kunth bamboo, which is widely available in Colombia, over wood framing elements. Using a simplified nonlinear model of the general cyclic response of shear walls (SAWS), the structure was subjected to various ground motions representative of local seismic demand conditions, and performance parameters were estimated for assessing its behaviour. Results indicate that the five–story laminated Guadua bamboo framed building has an adequate performance under seismic demands, and could be considered as a potential alternative material for the construction of low– and mid–rise buildings in Colombia.
