Development of reinforced method of historic masonry buildings by steel in consideration for design and workability

对历史砌体建筑进行了振动测量和分析，在考虑设计和可行性的基础上提出了加固方法。对使用钢框架和/或钢筋混凝土剪力墙加固前后的砖石建筑进行了微震测量。从而了解了平面外固有频率、振型和阻尼系数的变化。在无加筋墙体下，基于厚板理论进行了模态分析，并提出了1^<st>固有频率的估算公式。

I carry out vibration survey and analysis of historic masonry buildings forward construction of reinforced methods in consideration for design and workability. Microtremor measurements conducted for masonry buildings before and after reinforcement used by steel frame and/or RC shear walls. So we understand the change of out-of-plane natural frequencies, vibration mode and damping factor. Under unreinforced walls, I conduct mode analysis and proposal of estimation formula of 1^<st> natural frequency based on thick plate theory.
