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