Abstract

This study is a follow-utilization of water hyacinth as a building material wall panel (Emen wall). From previous studies, physical properties, mechanical, acoustic and endurance burn this material meets the standards of building materials PUBI 1982 and ISO and ASTM C423-90a 03-6861.1-2002. In this study, the variable still is a variation of the test specimen without reinforcement with reinforcement of bamboo and bamboo in the form of a model variation of the beam section size (15x20cm) and sectional plates (5x15cm). While the independent variable is in the form of bending strength and deflection in the test specimen. The results showed the effect of bamboo reinforcement against bending strength cement panel hyacinth. On the test object model of the beam section with bamboo reinforcement ratio r = 0, r= 0.006 and r = 0.01 , powerful bending P = 24kg, P = 59kg and P = 72kg. To model the cross section of the plate with a bamboo reinforcement ratio r = 0, r = 0.017 and r = 0.025 , stronger bending is P = 3,33kg, P = 16,33kg  and P = 21,83kg.

Abstract

Structural response of concrete of pillar commonly happened from the result of in site testthrough loading test. But, the test needs large amount. So, it is suggested to use an efficient analysismethod through simulation of numeric model. A model of pillar on the homogeny land will be loadedby a horizontal weight. By considering strengthen of the pillar and the reaction of the ground, tosolve the accountability can be done by using finite differences method. For example, for a concreteof pillar 30x30cm with a lateral weight 1000kg are have lendutan response ymaks=42mm, while themaximum moment response Mmaks=780kg.mKeyword: concrete response, lateral weight, finite differences method.
