Selection of appropriate intensity measure for collapse capacity prediction of low to mid-rise steel special moment resisting frames [PDF]

open access: yesJournal of Structural and Construction Engineering, 2017
A parameter that quantitatively represents the strength of a ground motion is called Intensity Measure (IM). The value of an IM for a given hazard level is the output parameter of Probabilistic Seismic Hazard Analysis (PSHA) which is used in structural ...

Intensity Measure Based on a Smooth Inelastic Peak Period for a More Effective Incremental Dynamic Analysis

open access: yesApplied Sciences, 2020
The Incremental Dynamic Analysis (IDA) assesses the global collapse capacity of a structure by plotting its maximum inelastic response, obtained through a non-linear time-history analysis, versus the scaled intensity of different input earthquakes.

适用于全周期结构的速度脉冲型地震动强度表征参数研究

open access: yesDizhen xuebao, 2019
鉴于传统的地震动强度表征参数(IM)不能有效地反映速度脉冲型地震动的破坏特征,需要研究能够在全周期段内表征速度脉冲型地震动强度的参数。本文首先从NGA-West2强震数据库中选取了236条速度脉冲记录,分析了42种地震动参数之间的相似性和相关性,初步给出了速度脉冲型地震动强度的表征参数;其次,利用单自由度体系动力时程分析方法,研究了不同延性μ条件下速度脉冲型地震动强度表征参数与最大非线性位移um之间的相关性系数随周期T的变化特征 ...
