[ 1 ] - Evaluation of Performance Levels of Zipper-Braced Frames Using Structural Damage Index
The determination of structural and nonstructural damage under earthquake excitations is usually considered as a key factor in performance-based seismic design (PBSD) methods is In this regard, various damage indices have been developed in recent years to quantitatively estimate structural damage. The aim of this study is to develop a simple method to evaluate performance levels of zipper-brace...
[ 2 ] - Soil Structure Interaction Effects on Hysteretic Energy Demand for Stiffness Degrading Systems Built on Flexible Soil Sites
This paper aims to study the influence of soil-structure interaction on plastic energy demand spectra directly derived from the energy-balance equations of soil-shallow-foundation structure with respect to an ensemble of far-field strong ground motions obtained from Pacific Earthquake Engineering Research (PEER) database and recorded on alluvium soil. The superstructure is modeled as a single-d...
[ 3 ] - Achievement of Minimum Seismic Damage for Zipper Braced Frames Based on Uniform Deformations Theory
When structures are subjected to strong ground motion excitations, structural elements may be prone to yielding, and consequently experience significant levels of inelastic behavior. The effects of inelastic behavior on the distribution of peak floor loads are not explicitly accounted for in current seismic code procedures. During recent years, many studies have been conducted to develop new de...
[ 4 ] - An Intensity Measure for Seismic Input Energy Demand of Multi-Degree-of-Freedom Systems
Nonlinear dynamic analyses are performed to compute the maximum relative input energy per unit mass for 21 multi-degree-of-freedom systems (MDOF) with preselected target fundamental periods of vibration ranging from 0.2 to 4.0 s and 6 target inter-story ductility demands of 1, 2, 3, 4, 6, 8 subjected to 40 the earthquake ground motions. The efficiency of the several intensity measures as an ind...
[ 5 ] - Seismic Evaluation of Flexible-Base Low-Rise Steel Frames Using Beam-On-Nonlinear-Winkler-Foundation Modeling of Shallow Footings
Recent investigations have shown that the influences of Soil-Structure Interaction (SSI) may be detrimental to the seismic response of structure, and hence neglecting this phenomenon in analysis and design may lead to an un-conservative design. The objective of this paper is to quantify the effects of nonlinear soil-structure interaction on the seismic response of a low-rise special moment fram...
[ 6 ] - اثر وابستگی سختی دینامیکی خاک به فرکانس زلزله و تأثیر پارامترهای اندرکنشی بر پاسخ ارتجاعی و غیرارتجاعی سیستم‌های خاک - سازه
در تحلیل و طراحی لرزه‌ای سازه ها عموماً فرض می‌شود که خاک زیر شالوده صلب است و از انعطاف پذیری آن صرف نظر می‌گردد. با در نظر گرفتن انعطاف پذیری خاک زیر پی، انتظار می‌رود که پاسخ سازه تحت تأثیر متقابل اندرکنش دینامیکی سیستم خاک و سازه قرار گیرد. به طور کلی مقادیر مختلف پارامترهای موثر خاک و سازه بر پاسخهای لرزه ای تأثیرات متفاوتی خواهند گذاشت. در این مطالعه با استفاده از یک تحلیل پارمتریک، اثرات ...
