Abstract:

The behaviour and design of prestressed steel structures, with an emphasis on trussed arches, are examined in this thesis. For long-span structural systems, where self-weight becomes an increasingly dominant component of the design loading, significant material savings can be achieved through the use of high tensile strength steel cables in conjunction with conventional steelwork. Further benefits can be achieved by prestressing the cables. In the system currently being investigated, the prestressed cables, which are housed within the bottom chord of tubular arched trusses, apply a compressive

Abstract:

An investigation of prestressed concrete containing steel fibres as secondary reinforcement to improve performance in shear, flexure and bond is reported. Emphasis is placed on the use of steel fibres in prestresssed extruded hollow core slabs, since these common precast elements have intrinsic difficulty in incorporating traditional secondary reinforcement due to their unique shape and manufacturing method. Two separate studies were carried out. The first study involved laboratory investigations into the bond between fibre reinforced concrete (FRC) and the prestressing strand, and the shear b

Abstract:

This study investigates the use of Carbon fibre-reinforced polymer (CFRP) tendons on precast segmental concrete bridge beams (PSBs). Experimental and numerical results have approved the feasibility of applying CFRP tendons on this type of structure in construction practice for corrosion control that allows to reduce lifecycle maintenance costs of the structure. A new analytical procedure for predicting deflections and closed-form equations to estimate the balanced reinforcement ratio of PSBs with unbonded tendons are also developed.

Bridges and other coastal structures in Georgia and throughout the Southeast are deteriorating prematurely due to corrosion.

The use of stainless steel alloys in reinforced concrete structures has shown great success in mitigating corrosion in even the most severe of exposures. However, the use of high-strength stainless steels (HSSSs) for corrosion mitigation in prestressed concrete (PSC) structures has received limited attention. To address these deficiencies in knowledge, an experimental study was conducted to investigate the feasibility of using HSSSs for corrosion mitigation in PSC. The study examined mechanical behavior, corrosion resistance, and techniques for the production of HSSS prestressing strands. Stai

Abstract:

This research developed a new method to investigate the construction stage effects on the behavior of pre-stressed steel structures. Any changes of structural geometry and/or material properties are properly accounted and evaluated stage-by-stage during the whole construction. Therefore, the structural responses are properly predicted. Any instability and excessive deflection of structural members or the possibility of structural collapse during construction can be avoided.

Abstract:

Prestressed concrete piles are commonly used to support over-water highway bridges in marine environments. The reinforcing steel within will ultimately be degraded via corrosion damage due to the penetration of chloride ions from sea water. The service life of these structures is, in part, dictated by the time required to diffuse chloride ions through the concrete cover and subsequently corrode the steel. Therefore, by slowing the rate of diffusion or increasing the chloride threshold of the steel (or both) an increased service life can be expected. This thesis focuses on the latter whereby st

Abstract:

This thesis is focusing on general issues of floor concrete slabs, technology, implementation, subsoil models, calculation of internal forces and design approaches. Based on these data the thesis monitors the behaviour of floor slabs according to the various parameters. It also includes three versions of design of the real floor slab, made of steel fibre reinforced concrete, reinforced concrete and prestressed concrete. Economic comparison is also included. In addition it developes a design of the chalice base and reinforced concrete column of the supporting hall system, instead of the origina

Abstract:

The matter of this thesis is static design and examination of prestressed storage tank to 50000 tons of sugar. Computational model of the steel roof structure is processed and its effect on the silos. Loads is provided of sugar. Optimal design is performed and assessment ultimate and serviceability limit state reinforced concrete and prestressing horizontal silo wall including local load. Next, it is performed the design of a reinforced concrete of the plane bed and column and assessment at the ultimate limit state. The thesis is also drawing documentation, technical report and visualization o

Abstract:

The thesis is a design of a bridge crossing the valley of the Hrabyňka creek as a part of road I/II. Firstly, three possible structures are designed and according to their advantages and disadvantages, the best of them is selected. In this case a cable stay bridge was selected. Following is a design of span lenghths, collumn heights and the cross-section. Then the loads are detremined and applied on a numeric model cretaed in software working on the basis of FEM. In continuation internal forces are calculated and their propriate combinations for service limit stay and ultimate limit state with

Abstract:

In this diploma thesis two steel frame objects of a waste dump in Úholičky are solved. The aim is to resolve the chosen parts of a construction-technological project. The main topics for selected technological phases are transportation, bill of quantities, technological regulations, construction organization’s principles, time schedule, machinery, control and testing plan, work safety and worker’s health protection. These topics are prepared for the technological phases of ground works, fundamental contruction, upper load-bearing structure, construction of the floor and sheathing of the object
