Shaking table test of wooden framed structure was conducted under light,moderate or heavy dead load. The dead weight to wooden fame was changed for 2.0kN/㎡,4.0kN/㎡,or 5.9kN/㎡,and the maximum acceleration level of the input earthquake excitation was increased from 200cm/s^2 to 2,000cm/s^2 gradually. Fundamental dynamic behavior of one-story,one-bay wooden frame with or without braces and/or plywood panel walls was investigated. The influence on a natural period and a response magnification of the structure is focused. Moreover,the effect due to vertical vibrations (up and down) and specifications of beam-to-column joint connectors are also considered. In conclusions,the following were clarified. Natural period of the elasticity limit,Te,of wooden framed structure was proposed as an evaluation index of damage at the earthquake. It is defined as the structural damage in plasticity when the natural period exceeds Te. Executing the static loading test,a natural period ofthe elasticity limit,Te,was calculated using equivalent elasticity rigidity. |
