Optimum seismic and wind resistant design for buildings with hysteretic damping.

1995年科比地震后，我们考虑了建筑物和结构抗震设计的新方向。近年来，各种钢被用作结构材料。例如，低屈服点钢与普通钢的主框架组合，用作滞回阻尼器。该阻尼器是一种利用塑化滞后回线吸收振动能量的装置。这对抗震设计是一种期待。然而，更好的抗震设计并不一定对应于更好的抗风设计。本研究从抗震和抗风两个角度寻求建筑物结构设计的最佳解决方案。本文研究了建筑物在强风和强震作用下的弹塑性性能。还检查了各种滞回阻尼装置，以估计其性能。我们考虑了最佳的抗震和抗风设计的建筑物与滞后阻尼。

After the Kobe earthquake in 1995, we consider a new direction in seismic design of buildings and structures. Recently various steels are utilized for structural material. For example, low yield-point steel is combined with main frame of ordinary steel, and used as a hysteresis damper. This damper is a device to absorb the oscillation energy by hysteresis loop of plasticization. It is expecting for seismic design. However better seismic design does not necessarily correspond to better wind-resistant design. This research pursues the optimum solution for structural design of buildings from both of a seismic and a wind resistant points of view. We investigate the elasto-plastic behaviors of buildings in strong wind as well as strong earthquake. Also various devices for hysteretic damping are examined in order to estimate their performances. We take into consideration the optimum seismic and wind resistant design for buildings with hysteretic damping.
