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

1995年神户大地震后，我们思考了建筑结构抗震设计的一个新方向。最近，各种钢被用作结构材料。例如，将低屈服点钢材与普通钢材的主框架相结合，作为滞回阻尼器。该阻尼器是一种通过塑化滞后环吸收振动能量的装置。期待对抗震设计有所裨益。然而，更好的抗震设计并不一定与更好的抗风设计相对应。本研究从抗震和抗风两个角度寻求建筑结构设计的最优解。研究了建筑物在强风和强震作用下的弹塑性行为。此外，还考察了各种滞回减振装置，以评估它们的性能。我们考虑了滞回阻尼器的最优抗震和抗风设计。

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.
