Overstrength of Displacement-Based Designed Eccentrically Braced Steel Frames [PDF]

Journal of Structural and Construction Engineering, 2016
Direct Displacement-Based Design (DDBD) is a performance-based seismic design method that has been proposed and developed over the past two decades for RC frame structures, shear walls and bridges design. The aim of this study is to evaluate overstrength

Nonlinear Dynamic Analyses Utilising Macro-Models of Reinforced Concrete Building Structures and Site-Specific Accelerograms

CivilEng, 2023
This paper aims to guide structural engineers on how to apply the rapid nonlinear time history analysis (RNLTHA) procedure effectively to predict seismic demand, taking into account ductility and overstrength, and effects of dynamic phenomena including ...

Seismic Performance of CFST Frame-Steel Plate Shear Walls Connected to Beams Only

Shock and Vibration, 2021
The safety and cost of structures composed of concrete-filled steel tube (CFST) frame-steel plate shear walls (SPSWs) with two-side connections are governed by the seismic performance.

Predictive modelling and latent space exploration of steel profile overstrength factors using multi‐head autoencoder‐regressors

ce/papers, 2023
AbstractThis paper investigates the suitability and interpretability of a data‐driven deep learning algorithm for multi cross sectional overstrength factor prediction. For this purpose, we first compile datasets consisting of experiments from literature on the overstrength factor of circular, rectangular and square hollow sections as well as I‐ and H ...

Seismic Vulnerability of Non-Code-Compliant and Code-Compliant RC Buildings

Structural Mechanics of Engineering Constructions and Buildings
This study investigates the seismic vulnerability of non-code-compliant reinforced concrete (RC) buildings compared to code-based structures. The research uses linear elastic and nonlinear pushover analyses (NPA) to evaluate critical seismic performance ...

Effect of the transverse reinforcement spacing in nodal zones on the seismic behavior factor of RC frames according to Algerian design code RPA99/version2003

Journal of Building Materials and Structures
The seismic behavior of reinforced concrete (RC) frames is significantly influenced by the confinement provided by transverse reinforcement. This study investigates the effect of transverse reinforcement spacing on the seismic behavior factor (R) of ...

Effects of higher modes and MDOF on strength reduction factor of elastoplastic structures under far and near-fault ground motions

Ain Shams Engineering Journal, 2017
In seismic codes, the force strength reduction factor is proposed to transform elastic to inelastic strength. The ductility reduction factor, Rμ, plays a key role on R factor if no overstrength is present. The Rμ is determined by SDOF systems.

Seismic Design and Performance Assessment of Frame Buildings Reinforced by Dual-Phase Steel

Applied Sciences, 2021
To improve the durability and serviceability of reinforced concrete structures, different variants of dual-phase reinforcing steel were developed within the research project NEWREBAR. The investigated variant of the new material, termed DPD2 steel, has a

Overstrength and Response Modification Factor in Low Seismicity Regions

Journal of the Earthquake Engineering Society of Korea, 2006
Seismic design codes are mainly based on the research results for the inelastic response of structures in high seismicity regions. Since wind loads and gravity loads may govern the design in low seismicity regions in many cases, structures subjected to design seismic loads will have larger overstrength compared to those of high seismicity regions ...
