Response of Buildings with Inclined First-Story Columns to Near-Fault Ground Motion [PDF]
Journal of Rehabilitation in Civil Engineering, 2014 In this paper a simple model of a three story building with inclined first-story columns has presented. The stories are supposed to be rigid and are connected to axially rigid mass less columns by elasto-plastic rotational springs and linear rotational ...

Seismic behavior of MSCSS based on story drift and failure path [PDF]
Latin American Journal of Solids and Structures, 2021 Abstract The Mega-Sub Controlled Structure System (MSCSS) is a new type of seismic structural system. This research aims to find weak members in the structure and better describe the failure state. To achieve this, we enhanced the story drift ratio indicator by combining it with the structural failure path and proposed a new comprehensive indicator ...

Seismic Retrofitting of Steel Frames with Buckling Restrained and Ordinary Concentrically Bracing Systems with Various Strain Hardening and Slenderness Ratios [PDF]
Journal of Rehabilitation in Civil Engineering, 2014 The present study assesses the seismic performance of steel moment resisting frames (SMFs) retrofitted with different bracing systems. Two structural configurations were utilized: ordinary concentrically braces (OCBFs), buckling-restrained braces (BRBFs).

Evaluation of Seismic Behavior of Steel Shear Wall by Time History Analysis [PDF]
Computational Engineering and Physical Modeling, 2019 Reducing the vulnerability of buildings against earthquakes is one of the most important issues for engineers and public concern in the last decade. For designers, choosing the best option among the different lateral bracing systems that exist in terms ...

Seismic damage assessment of subway station subjected to mainshock-aftershock sequences
Yantu gongcheng xuebao, 2023 In the previous seismic analyses of underground structures, only the peak structural response under the main earthquake is considered, but the damage mechanism of underground structures subjected to sequential ground motions has not been fully understood

Evaluating of Relative and Absolute Cumulative Input Energy Time History subjected to Forward Directivity Earthquakes [PDF]
Numerical Methods in Civil Engineering, 2021 In this article, to study the effect of pulse-type near-fault earthquakes on the seismic demands of steel moment frames, 15-story 2D-frame was analyzed under the influence of 20 near-fields with forward directivity effect and 2 far-field records.

Evaluation of seismic design provisions for a drift and inter-story drift relationship [PDF]
WIT Transactions on The Built Environment, 2015 Maximum roof drift (RD) and inter-story drift (ISD) demands are important seismic design parameters since they are used to evaluate seismic hazard levels and performance state for structures located in seismic regions. ISD demand, especially, is an important seismic design parameter for evaluation of seismic performance of both structural and non ...
