ABSTRACT

The use of plate materials such as structural steel is growing rapidly. Several studies have been conducted on the characteristics of thick plates using contrasting deflection functions, theories and methods to investigate their structural performance. The remarkable benefits of this structural materials to many engineering applications has grown its research horizon. A thorough review was done in this paper to keep a quick glance of this exceptional construction material. This paper describes elaborately bending, buckling and vibration behaviour of thick places. The knowledge of this reviewed works is crucial for framing engineering edifices. The outcome of this study will assist researchers and scientists to spot pertinent prevailing literatures quickly and enhance further studies. The elasticity theories employed by several scholars, the displacement functions, and the support conditions that were addressed, were encapsulated in this research work. Most studies reviewed in this paper focused on plates whose support-status were simply-supported at all the edges (SSSS) and clamped-supports at all the edges (CCCC). The outcome of this study based on review of previous studies showed that refined plate theories (RPTs) underestimates and over-anticipates stresses, displacements, frequencies and loads due to the supposition of deformation kinematics and negligence of the elements along the thickness-locus of the plate. This paper revealed that three-dimensional (3D)-plate theories are preferable and reliable since they produce accurate and exact solutions for thick plates. This work promotes sustainability in the construction industry and equips potential practitioners with adequate knowledge that strengthens choice-making on projects that require their utilization.
