Probabilistic seismic performance estimation through surrogate model and unbiased multi‐fidelity Monte Carlo predictor
Autor: Xiaoshu Gao, Jun Iyama, Tatsuya Itoi
Publikováno v: Japan Architectural Review, Vol 7, Iss 1, Pp n/a-n/a (2024)
Abstract This study introduces an approach for probabilistic seismic performance estimation, which focuses on the probability of intensity measures exceeding a specified value based on engineering demand parameters. Conventional methods face challeng

Threshold value and applicable range of nonlinear behavior detection method using second derivative of acceleration
Autor: Jun Iyama, Masaki Wakui
Publikováno v: Japan Architectural Review, Vol 2, Iss 2, Pp 153-165 (2019)
Abstract A previously proposed nonlinearity detection method using the second derivative “snap” of the recorded absolute acceleration requires the determination of a threshold value based on the yield strength of the target vibration system, whic

Shaking table test of steel truss frame focusing on acceleration and strain response for post-earthquake buckling evaluation
Autor: Jun Iyama, Chih Chun Ou, Satoshi Yamada, Kazuki Chiba, Manabu Toyoshima
Publikováno v: Bulletin of Earthquake Engineering. 21:2759-2783
Large-span steel structures have been widely adopted in stadiums, airports, factories, and train stations because they provide a large space for multi-functional use. To ensure business continuity, post-earthquake damage surveys and structural status

Probabilistic distribution estimation of residual deformation by numerical simulation considering variation and directivity of plastic deformations: Study on distribution of residual deformation after earthquakes, part 3
Autor: Jun Iyama, Hiroaki Shimokawa
Publikováno v: Japan Architectural Review, Vol 1, Iss 1, Pp 67-76 (2018)
Abstract This paper discusses a method to estimate the probability density function of the residual deformation of a bilinear single‐degree‐of‐freedom system with isotropic hardening or kinematic hardening; this method is more detailed compared
