碩士 / 國立臺灣科技大學 / 建築系 / 104 / Extensive concerns on environmental protection have provoked low-carbon buildings to be the mainstream of building construction worldwide, and timber structures in this sense outperform other structural forms. Timber-concrete hybrid structures featuring distinct timber and concrete stories typically exhibit uneven stiffness distribution along the structure height; in particular, abrupt stiffness changes occur at the timber-concrete transition stories. Therefore, structural designing of such hybrid structures must consider a stiffness amplification effect in the static structural calculation as well as complicated procedures in the dynamic analysis. To determine an appropriate amplification factor for design purpose, this study employed a dynamic numerical approach to determine the displacement response of timber-concrete hybrid buildings and compared the results with the displacement response obtained from static analyses. According to the results, it is found that the appropriate amplification factor should beα= f(x) = 0.47x + 1.00.αcan be valued 1.94 at 2nd floor, 2.41 at 3rd floor and 2.88 at 4th floor. The results may serve as a reference for seismic designing of timber-concrete hybrid structures.
