Cement is the second most used construction material on earth. Beside the decliningrnabundance of the raw materials to be used for the production of cement, the powerrnand energy saving problems has become the main questions of the world. The searchrnfor new smart construction materials and the recycling procedures are currently underrnresearch and practices. The efficient use of the materials could also be a significantrnfactor that could give out a valuable contribution in this regard.rnEconomy, sustainability and environmental changes become the main challenges ofrnengineers in the 21st century. In this thesis, analytic comparison is made by minimizingrnthe volume of concrete used for long and slender concrete piers in order to getrnbuckling and axial compression load resistance as well as economically efficientrnsections. Bridges of several height are designed and examined under similar Structuralrnloads.rnDuring casting, Concrete experiences different stages of hydrations. These chemicalrnreactions can be categorized as exothermic chemical reactions in which, heat will bernreleased. The amount of high heat released in the core center of the member will notrnbe migrated to the environment so easily and it will result in thermal stress and earlyrnstage cracks at the outer most surfaces. The crack formation can be kept minimum byrnreducing the Concrete volume, which actually results in less thermal stress.rnThe ductility property of various bridge piers are evaluated and hollow sectioned piersrnare found to be more ductile. For bridges built in the seismic areas, plastic momentrncapacity is calculated for piers of hollow and solid core sections. This sample piers arerndesigned with various height and the result indicate that sections of hollowrnrectangular piers are more ductile and economical.
