抄録 Tubular sections are commonly used for truss structures or diagonal braces, because
they have higher moment-of-inertia comparing to open cross-sections with the same area …

抄録 A moment frame with bracing elements is one of efficient seismic-resistant structural
system in elastic design, however, when the seismic input is larger than the buckling …

抄録 A series of shaking table tests on a high-rise building are conducted in order to assess
effects of retrofit using steel dampers. The specimen consists of a four-story steel frame and …

抄録 Structural system composed of high-strength steel frame with energy-dissipation
elements is one of the suitable solutions for damage tolerant structures. The main structure …

抄録 H-section braces are widely used for seismic-proof elements in various kinds of
structures. However, when they receive the cyclic loading beyond the expected seismic …

抄録 Cumulative deformation capacity is one of the most important benchmark for the
performances of elasto-plastic dampers within vibration-controlled buildings built in seismic …

抄録 The authors have proposed new concept of split-tee connections at bottom flanges of
beam ends, which work as beam-end elasto-plastic dampers. They are composed of small …

抄録 This study discusses a retrofit method for telecommunication steel towers by using
buckling restraint braces (BRB), and proposes a method to determine the optimum …

抄録 Wind load was critical for the design of tele-communication tower than earthquake load
so far, however, recently expected earthquake load become more critical than wind load …

抄録 Tubular sections are commonly used for truss structures or diagonal braces, because
they have higher moment-of-inertia comparing to H-sections or L-sections with the same …
