A 3D fibre beam-column element with shear modelling for the inelastic analysis of steel structures
Papachristidis, A.; Fragiadakis, M.; Papadrakakis, M. (2010)A force-based fiber beam-column element is proposed for the capacity assessment of frame structures under high shear. The proposed element is suitable for the performance assessment of large scale steel structures, which ... -
Evaluation of ASCE-41, ATC-40 and N2 static pushover methods based on optimally designed buildings
Lagaros, N. D.; Fragiadakis, M. (2011)Alternative static pushover methods for the seismic design of new structures are assessed with the aid of advanced computational tools. The current state-of-practice static pushover methods as suggested in the provisions ... -
Fast performance uncertainty estimation via pushover and approximate IDA
Fragiadakis, M.; Vamvatsikos, D. (2010)Approximate methods based on the static pushover are introduced to estimate the seismic performance uncertainty of structures having non-deterministic modeling parameters. At their basis lies the use of static pushover ... -
Improved seismic design procedures and evolutionary tools
Fragiadakis, M.; Lagaros, N. D.; Tsompanakis, Y.; Papadrakakis, M. (2006)Four alternative analytical procedures are recommended by the design codes for the structural analysis of buildings under earthquake loading. The objective of this chapter is to assess these procedures by integrating them ... -
MODELING, ANALYSIS AND RELIABILITY OF SEISMICALLY EXCITED STRUCTURES: COMPUTATIONAL ISSUES
Fragiadakis, M.; Papadrakakis, M. (2008)A critical review of the current state of the art of the computing practices adopted by the earthquake engineering community is presented. Advanced computational tools are necessary for estimating the demand on seismically ... -
Robust performance-based design optimization of steel moment resisting frames
Lagaros, N. D.; Fragiadakis, M. (2007)The concept of performance-based design is considered in the framework of Robust Design Optimization (RDO) for the design of steel structures. The RDO problem is treated as a two-objective optimization problem where the ... -
