| 要旨 | INTRODUCTION It is important that the natural period of building is far from the pre-dominant period of the 9round motion. Therefore, if structural designers are able to control the natural periods of buildings,they have a lot of benefits in the earthquake-resistant design.Such control-capability by Soft-First-Story (S.F.S.) is investigated and the possibility to control the natural period of building by the reduction of diameter of column and the increase of height of S.F.S is found.The purpose of this study is natural period by the usage of S. equations of the natural period to prove the possibility of controlling the natural period by the usage of S.F.S structure,and to propose the estimating that relate with the governing factors CONCLUSION Based on the study presented herein,the following conclusions can be (1)Changin9 in the stiffness distribution in upper stories and the weight distribution of entire building do not have influence on the natural periods in the case of building with Soft-First-Story.(2)The diameter reduction ratio of column and the height increase ratio of Soft-First-Story have a lot of influence on the natural periods,especially the latter factor has large influence on the natural periods.(3)The proposed equations are available to estimate the natural periods of concrete buildings with Soft-First-Story.The equations by simple regression method are simple and have practical applicability,and the equa tion induced from the theoretical study is accurate. |
