Sample Dissertation Outline for Civil Engineering
Dissertation outlines can be categorized into two types: simple outlines and detailed outlines. A simple outline is highly generalized and only hints at the main points of the paper, leaving out how to develop them. This kind of outline is simple but as it is composed after much thought, the writing goes smoothly. Here is a sample civil engineering dissertation outline that I am sharing with you, for more, please visit the thesis website.
Thesis topic: computational analysis of deflection of cast-in-place concrete hollow-core slabs and its control research
Cast-in-place concrete hollow-core slab is a new type of floor cover system, which has the advantages of large span, large space, and light deadweight, and it has been widely used in practical engineering in China. However, the current research on cast-in-place concrete hollow core slab is still imperfect, with the further increase of the span of hollow core slab, many problems including applicability need to be solved as soon as possible. In this paper, first of all, the bending stiffness of the hollow core slab in both directions is calculated and analyzed, and the formula for calculating the bi-directional stiffness of the hollow core slab taking into account the influence of transverse ribs is deduced to determine its orthotropic anisotropy and isotropy attribution; this paper transforms the hollow core slab into a solid slab according to the principle of equal stiffness, and analyzes the internal force based on the theory of bending of the elastic thin plate. Secondly, the deflection formula of in-situ cast-in-place hollow-core slab in elastic stage is derived according to the Ritz method. Considering the fact that the stiffness of the hollow-core slab decreases with the development of cracks, the deflection formula of the hollow-core slab in elastic-plastic stage is derived on the basis of the elastic deflection formula, which includes the orthotropic anisotropic plate and the isotropic plate under the action of homogeneous and line loads, respectively. In this paper, prestressing is introduced to control the deflection of cast-in-place concrete hollow-core slabs. It is considered that the prestressing force acts on the bottom surface of the slab in the form of a line load, which causes the inverted arch of the hollow-core slab. The counter-arching of the hollow core slab due to prestressing reduces its own deflection under load; this paper also gives a method to quantitatively calculate the prestressing. In this paper, the finite element software ANSYS is used to analyze the deflection of the hollow core slab with prestressing applied at the concealed beam under load. In the analysis, two models of ordinary hollow core slab and hollow core slab with prestressing applied in the concealed beam are established separately for the analysis. Finally, this paper carries out the hollow core plate model test with the scale of 1:8, and compares and analyzes the test results of the deflection of the hollow core plate, the results of ANSYS calculations and the results of the formula calculations.
