  • Comparison Between Membrane Theory and Finite Elements Analyses for Domed Shells Edged by Support Ring Beam 
    Khattab Saleem AbdulRazzaq; Waad A. Zakaria; Ali AlAmawy (University of Diyala – College of Engineering, 2013-09-01)
    Domes are back again in Iraq. They are early recognized with specific houses of those who consider them a symbol of Iraqi architecture, beauty and luxury at the same time. Nowadays, domes are widely implemented. Domes, ...
  • Dynamic Behavior of Sheet Pile in Sand under the Influence of Vibration 
    Noora J. Mousa; Waad A. Zakaria; Khaled Shahot (University of Diyala – College of Engineering, 2023-12-01)
    This article includes an experimental investigation into the behavior of a vibratory force-exposed sheet pile set in sand. The study goal is to provide a parametric study. Regarding how vibrations affect the sheet pile's ...
  • A Dynamic Response of Pile Foundation Subjected to Different Frequencies in Sandy Soil 
    Hanan J. Mohammed; Waad A. Zakaria (University of Diyala – College of Engineering, 2024-03-01)
    This research presents an experimental study of the dynamic response of pile foundation as a result of the vibration of a nearby foundation as a source of dynamic load in sandy soil with relative density of 85%. The ...
  • Predicting of Seismic Performance on Tunnel in Weak Soil 
    Nuha J. Najm; Waad A. Zakaria; Muftah Mohamed Sreh (University of Diyala – College of Engineering, 2023-06-01)
    Main seismic situations have appeared that the tunnels in weak soil may be suffer large seismic damage. Suitable modeling can have great significance for predicting and estimating their seismic acting. This paper examines ...
  • Prediction of Stresses and Settlement for TBM Tunnel Surrounding Soil 
    Halah Hashim Muhammed; Waad A. Zakaria; Qasim A. Mahdi (University of Diyala – College of Engineering, 2019)
    In recent years, modern technology in the construction of tunnels using tunnel-boring machines (TBM) is implemented in the practice of civil engineering in large cities which significantly reduces the harmful effects of ...
  • Reducing Effect of Vibration on Footing using Different Materials 
    Ali H. Hussein; Waad A. Zakaria (University of Diyala – College of Engineering, 2020)
    This paper investigates the reduction of vibration effect between two footings by placing a trench between them. On the first footing (designated as the source footing), on electric-rotary motor is fitted, it has dimensions ...
