    ABSTRACT: The response of structural components subjected to a stepped triangular blast loading had been the subject of a great deal of research. Much of these researches had been concentrated on the response of plates to impulsive loads. Complexity of these problem would increases appreciably when effects due to stiffeners configuration and effects of structural damping were considered. In this paper the behavior of orthotropic damped plates with different stiffener configurations subjected to a stepped triangular blast loading is described. The aim of this work is to determine the dynamic response of stiffened orthotropic plates to a stepped trianggular blast loading and to determine the effect of stiffeners configuration and blast loading duration on the plate failure. The natural frequencies of the orthotropic plate were solved from two transcendental equations, while the eigen functions of the system are solved using the Modified Bolotin Method (MBM). The stepped traingular blast loading is further integrated using the Duhamel integration method to find the total dynamic response of the system. The numerical results give new insight into the effect of stiffeners configuration, structural damping and time duration of the blast loading on the plate response.

    ABSTRACT: This article discusses the rationale for an interpretive paradigm in organizational research and examines two specific qualitative techniques that could help define organizational phenomena in a way that would account for organizational problems and issues. These are participative observation and in-depth interviewing which will be evaluated in a case scenario in a workplace context. These techniques have been found to be useful not only organizational research but in practical situations as well. Through an illustration of how security personnel perform their duty at work, we suggest that qualitative methodology can be applied in daily contexts to evaluate the capacity, understanding and the capability of these personnel in relation to their adherence to policy and procedure. It provides richness in terms of experiential narratives that depict the perception of surroundings that construct meanings, structures and actions. Qualitative methodology explores changing, complex social phenomena and helps in theory building and theory elaboration.
