Abstract
Domes are the most energy efficient and safest buildings that can be built and that can be designed for many uses. It is one of the most efficient shapes for covering large areas, for it encloses a maximum amount of space with a minimum surface area. Domes are thin shells so the dead weight is reduced and the structure free from large bending stresses. So the least amount of materials can be used and have the maximum structural advantage. Ferrocement appears to be an economic alternative material for roofing. It has a high tensile strength and stiffness and a better impact and punching shear resistance than reinforced concrete, because of two-dimensional reinforcement of the mesh system on a per volume basis, and undergoes large deformations before cracking or high deflections before collapse. This thesis explain the effect of selected parameters on the behavior of spherical domes. This parameters included types of materials used as: wire mesh-fabric, steel bars Ø6mm in each direction, Casting and testing four different spherical domes were investigated. One spherical dome has two layers welded wire meshes and without opening. The second dome has two layers welded mesh, and with opening (100x100mm). The third one was reinforced with two layers of fiberglass mesh and the fourth dome has one layer of polyethylene mesh. All spherical domes have the same dimensions;1000 mm diameter, 500 mm height. D1&D2 have 50mm thickness, D3&D4 have 60 mm thickness. Comparisons between the results of test specimens were conducted based on the parameters considered in this experimental investigation. Effect of these parameters were studied on the structural responses in terms of failure load, mode of failure, first crack load, and displacements, and Different properties were determined such as ductility ratio, energy absorption, and the service load, or flexural serviceability load. The finite element modeling of the domes was performed using Program ANSYS 11.0. It is a general purpose finite element modeling package for numerically solving a wide variety of mechanical problems. The process for a typical ANSYS analysis involves three general tasks: building the model, applying loads and obtaining solution, reviewing the results. The models were loaded up to ultimate loads and the efficiency of the model was verified by comparing the ultimate and cracking loads as well as the load deflection response with the experimental results. (SOLID65) was used to model the reinforced mortar layers, and (LINK8) was used to model steel reinforcement in finite element.
