Abstract

In the last five years, several earthquakes struck several places in Indonesia and thousands of people died caused of their masonry house. Therefore, the idea of bamboo utilization in the form of structural sandwich panel components for anti-seismic pre-fabrication house is one of appropriate way out. This research describes the performance and behavior of engineered structure wooden-bamboo sandwich panel in full sized test. The wall frame being use were meranti wood, this frame attached by plywood as face and back, then 5 em bamboo cutting as core; the fastener used in this study were isocyanate resin and nails. This study carried out by experimental data of full scale structural tests on shear wall (ISO 22452). These result showed that the seismic reliability of the wall frame system made of bamboo sandwich panel was appropriate and will be useful for prefabrication houses as anti-seismic and environment friendly residential building.

Abstract

Anatomically, bamboo is constructed from many types of cells. Vascular bundles are the cells which give the highest contribution to the bamboo strength, thus the density distribution of vascular bundles could be used as the main variable for analyzing the layer system of bamboo strip and laminated bamboo. The density of vascular bundles distribution decreases gradually from the outer to inner part in a regular manner which could be fitted by linear or nonlinear function. Ratio of modulus of elasticity (E) which widely used in transformed cross section (TCC) method for analyzing the layer system are substituted by ratio of density distribution of vascular bundles with asumption that both are highly correlated. The data in this study proved that there are high Pearson’s corellation between the theoretical and the empirical result, and the paired t-student test also showed both are not significantly different; thus, this new method could be applied in very good result. There are 3 models applied in this study, namely linear, logarithm, and power. Power model is the best among others since its theoretical gives the nearest estimation to the empirical measurement.

Abstract

Bamboo is a natural resource that can be used as a basic commodity to substitute wood. To determine the use of a basic commodity, it is needed to study the basic characteristic of bamboo, in terms of anatomy, physical, and mechanical properties. Some studies of this topic, especially for engineering purpose, have been done, but the most of them used sample experiment in the form of bamboo culm. Therefore, it is necessary to find out whether experiments using bamboo strip are equivalent with the value of bamboo culm. This study used tali and ampel bamboos. The anatomy observation followed the Manual of Anatomy Practical Work and Wood Identification by Pandit (1991) and Nuryatin (2000), tests were based on Nuryatin’s study (2000). Sample tests for mechanical properties were based on ASTM D 143-94 and modification of ISO 22157-1:2004. The results showed that physical properties of internode of tali bamboo were inferior than that of the node, in contrary to ampel bamboo, which was better than that of the node. For all mechanical properties, internodes of tali and ampel bamboos were better than that of the node. The modulus of elasticity of the bamboo culm was lower 110% than that of the bamboo strip and the modulus of rupture of the bamboo culm was lower 230% than that of the bamboo strip. On the other side, τTk// of the bamboo culm was 15% higher than that of the bamboo strip.
