comparison of nonlinear response of gravity cantilever retaining walls and mechanically stabilised earth (MSE) wall structures
Kamalzadeh, A., & Pender, M. Bulletin of the New Zealand Society for Earthquake Engineering, 55(2), pp.129–137, May 2022
During the past few decades, gravity cantilever retaining walls (GRW) have shown a relatively reliable performance. However, mechanically stabilised earth (MSE) retention systems have grown in popularity as they are cost-effective and have demonstrated resilience through recent seismic events. In…
insights from advanced numerical modelling into the pseudo-static design of gravity retaining walls
A. Kamalzadeh, M. Pender, 7th International Conference on Earthquake Geotechnical Engineering, Italy, April 2019
Results of numerical modelling of gravity retaining walls using the OpenSees finite element facilities are presented. Simplified design analyses for gravity walls are often based on pseudo-static modelling. The purpose of the paper is to check on the validity of…
modelling the dynamic response of gravity retaining wall systems using opensees
A. Kamalzadeh, M. Pender, 7th International Conference on Earthquake Geotechnical Engineering, Italy, April 2019
Recent work using the OpenSees finite element software to model the response of gravity retaining walls to Ricker wavelets is presented. The behaviour of the wall system during earthquake loading is controlled by the capacity of the shallow foundation supporting…
numerical investigation of gravity retaining wall foundation failure mechanisms
A. Kamalzadeh, M. Pender, 11th Pacific Conference on Earthquake Engineering, Auckland, April 2019
This research investigates the response of the gravity retaining walls subjected to monotonic and sinusoidal loadings, adopting the OpenSees finite element analysis. Recent research has shown the capacity of the shallow foundation supporting the wall controls the behaviour of the…
effect of column to beam plastic modulus index on seismic damage mechanism of steel moment frames
A. Kamalzadeh, R.K. Mohammadi, 7th International Conference on Acoustics and Vibration, Iran, November 2017
In order to secure adequate ductile behavior and high seismic damage capacity of steel moment frames during an earthquake, AISC 341 represents a strength criterion. According to this criterion, the moment capacity of columns must be more than the moment…
a simple approach for estimating ultimate curvature of structural steel sections
A. Kamalzadeh, R.K. Mohammadi, 5th National Conference on Earthquake & Structure, Iran, April 2014
Ultimate state of structural members has been widely used for the purpose of seismic design and rehabilitation in seismic standards. Even, common damage indices such as Park and Ang use ultimate state of structural response, known as ultimate deformation. This…
investigation on effective parameters for seismic damage control of steel moment frame
A. Kamalzadeh, R.K. Mohammadi, International Conference on Acoustics and Vibration, Iran, December 2013
In recent building standards, seismic damage of structures represents by local or global dis-placements and rotations. However, the effect of dissipated energy of members and the whole structure is not participated directly. Therefore, several damage indices are developed, containing the…
