The analysis of shallow shells with random variable curvature by asymptotic method

  The paper intends to survey and assess the random change of the form in the shallow shells, which is caused by the usual faults in the technology construction, the influence of which is ignored by the use of safety factors. The surface of the shallow shells with the random function is modulated by the asymptotic method, surveying the stress and strain in the shell. The results of the research can be used in...

Drift analysis due to earthquake load on tall structures

  Earthquake is one of the destructive events in the world. Prediction of earthquake is not feasible at all. In the horizon, earthquakes of different intensities and magnitudes occurred. So it is a threat to all especially the tall structures of the mega cities. Due to shaking of ground surface, the substructure as well as the superstructure is vibrated. During earthquake, there will be a drift on the high rise...

Development of a wind tunnel model compared with results of method of initial parameters and BS6399 models for dynamic analysis of multi-storey building subjected to aerodynamic loadings

  The research investigated the development of a wind tunnel model compared with results of method of initial parameters and BS6399 models for dynamic analysis of a multi-storey building subjected to aerodynamic loadings. The dimensional analysis which based its concept on the law of motion and energy conservation was used as wind tunnel experimental data assessment tool, for the determination of the...
