Seismic Assessment of Existing RC Buildings
2003Two procedures are presented for seismic assessment of individual RC buildings on the basis of member seismic chord rotation demands. In the (simpler) “preliminary” evaluation procedure, inelastic chord rotation demands are estimated from linear analysis, while forces for brittle failure modes are computed in a capacity-design fashion.

Analysis of RC Buildings by Metamodel Approaches
2020Response of RC structures is very complex and dynamic in nature because of the vulnerabilities that exist in geometry, material properties and loading. To represent the random dynamic responses accurately, stochastic analysis is chosen here. The stochastic analysis can be done by two types of methods, like statistical and the non-statistical approaches.

Structural Strengthening of RC Buildings for Enhanced Seismic Resistance
2020This study aims to present a strengthening technique for the seismic resistance of existing reinforced concrete (RC) buildings subjected to earthquake effects. The entire process is illustrated with a case study of an existing RC building. In this study, the building is examined with field surveys and numerical analyses.

Seismic Assessment of RC Frame Buildings
2016In the chapter, the N2 method and the non-linear dynamic analysis (NDA) are applied for the assessment of seismic performance of two variants of a 4-storey reinforced concrete (RC) frame building. The first variant is represented by the bare frames, whereas in the second variant infill panels are included in the upper three storeys, thus creating a ...

Extreme Modal Combinations for Pushover Analysis of RC Buildings
Key Engineering Materials, 2013The pushover method is a practical procedure for comprehensive nonlinear analysis of structures subjected to seismic action. Application of this method, in accordance with the Eurocode 8 rules and due to engineering simplicity, favours application utilizing the first mode.

THE EFFECTS OF THE SEISMIC INPUT ON THE SEISMIC RESPONSE OF RC BUILDINGS
Proceedings of the 5th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2015This work is aimed at investigating the variation of the seismic response of RC structures subjected to different ensembles of ground motions in the nonlinear dynamic analy-sis for the seismic assessment of existing RC buildings. At the current time indeed, all the main International Seismic Codes provide a soil classification which is based on the ...

In this paper it is investigated the performance of a hybrid control system for the reduction of the seismic vulnerability of existing reinforced concrete (RC) asymmetric structures with coupled modes. For this kind of structures the purely passive control system is not always able to warrantee an effective response control, due to the modal coupling ...

Knowledge-Based Performance Assessment of Existing RC Buildings
Journal of Earthquake Engineering, 2011One of the most challenging aspects of the seismic assessment of existing buildings is the characterization of structural modeling uncertainties. Recent codes, such as Eurocode 8, seem to synthesize the effect of structural modeling uncertainties in the so-called confidence factors that are applied to mean material property estimates.

EFFECTS OF “REINFORCED” INFILLED FRAMES ON EXISTING RC BUILDINGS
Proceedings of the 4th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2013), 2014This paper presents some considerations about the role of strengthening interventions involving the solidarization of the infill panels to the RC frame on the seismic retrofitting of existing buildings. Within this context, an appraisal of the actual resulting displacement capacity and of possible alteration induced on the global collapse mechanism and
