• Analysis of the effect of the seismic gap on the response of buildings experiencing pounding during earthquakes

  Publikacja

  - AIP Conference Proceedings - Rok 2023

  The aim of this paper is to investigate the effect of the seismic gap on the dynamic response of buildings experiencing earthquake-induced pounding. Three buildings have been analysed, which are 5-storey, 7-storey and 9-storey structures. Three possible pounding scenarios have been considered, which are pounding between 5-storey and 7-storey buildings, pounding between 5-storey and 9-storey buildings and pounding between 7-storey...

• Assessment of codes recommendations for the evaluation of the seismic gap of buildings founded on different soil types

  Publikacja

  • M. Miari
  • R. Jankowski

  - AIP Conference Proceedings - Rok 2023

  Several equations have been proposed in the literature to evaluate the seismic gap preventing earthquake-induced structural pounding, such as the ones based on the absolute sum of the peak displacements (ABS), the square root of the sum of the squares (SRSS), the double difference method (DDC), Australian code and the approach proposed by Naderpour et al. The aim of this paper is to investigate the accuracy of these equations taking...

• Influence of separation gap on the response of colliding models of steel structures under seismic and paraseismic excitations

  Publikacja

  - Rok 2016

  As a result of high urbanization, the need to erect closely-spaced buildings forces designers to consider collisions between structures taking place during ground motions. Experimental and numerical studies have confirmed that such collisions (often referred to as structural pounding) may cause serious damage to the structural elements and even lead to total collapse of colliding structures. The main reason of earthquake-induced...

• Seismic gap between buildings founded on different soil types experiencing pounding during earthquakes

  - EARTHQUAKE SPECTRA - Rok 2022

  Several formulas have been suggested in the literature to evaluate the minimum seismic gap that would prevent collisions between adjacent buildings during earthquakes, including those based on the absolute sum of the peak displacements (ABS), square root of the sum of the squares (SRSS), the double difference method (DDC), Australian code, and approach proposed by Naderpour et al. The aim of the present study is to evaluate the...

• An ANN-Based Approach for Prediction of Sufficient Seismic Gap between Adjacent Buildings Prone to Earthquake-Induced Pounding

  Publikacja

  - Applied Sciences-Basel - Rok 2020

  Earthquake-induced structural pounding may cause major damages to structures, and therefore it should be prevented. This study is focused on using an artificial neural network (ANN) method to determine the sufficient seismic gap in order to avoid collisions between two adjacent buildings during seismic excitations. Six lumped mass models of structures with a different number of stories (from one to six) have been considered in...

• Effective Equations for the Optimum Seismic Gap Preventing Earthquake-Induced Pounding between Adjacent Buildings Founded on Different Soil Types

  Publikacja

  • M. Miari
  • R. Jankowski

  - Applied Sciences-Basel - Rok 2023

  The best approach to avoid collisions between adjacent structures during earthquakes is to provide sufficient spacing between them. However, the existing formulas for calculating the optimum seismic gap preventing pounding were found to provide inaccurate results upon the consideration of different soil types. The aim of this paper is to propose new equations for the evaluation of the sufficient in-between separation gap for buildings...

• Machine learning-based seismic fragility and seismic vulnerability assessment of reinforced concrete structures

  Publikacja

  • F. Kazemi
  • N. Asgarkhani
  • R. Jankowski

  - SOIL DYNAMICS AND EARTHQUAKE ENGINEERING - Rok 2023

  Many studies have been performed to put quantifying uncertainties into the seismic risk assessment of reinforced concrete (RC) buildings. This paper provides a risk-assessment support tool for purpose of retrofitting and potential design strategies of RC buildings. Machine Learning (ML) algorithms were developed in Python software by innovative methods of hyperparameter optimization, such as halving search, grid search, random...
