The computation of temporal variation of clear-water scour is important for the design of bridge foundations. Previous studies implied that a very long flow duration is needed to achieve equilibrium scour at bridge abutments. However, the corresponding durations in the prototype conditions may yield considerably greater values than the time to peak of most of the design floods of small to medium sized catchment basins. Therefore, there is a need to estimate the temporal variation of scour depth. This study deals with development of a semi-empirical model for determining the time-dependent variation of clear-water scour depth at vertical-wall abutments. This approach applies the sediment continuity equation to a scour hole around a vertical-wall abutment. A sediment pickup function was used to formulate the rate of sediment transport from the scour hole. The results of the proposed model were compared with those of empirical models. The model agreed well with the test results.

Analytical and experimental investigation of temporal variation of clear water scour depth at bridge abutments
Köse, Ömer; Yanmaz, Ali Melih; Department of Civil Engineering (2007)
Computation of temporal variation of clear water scour is important for the design of bridge foundations. Previous studies conducted for determining equilibrium scour depth at bridge abutments indicated that very long flow duration was needed to achieve equilibrium scouring situations. However, the corresponding durations in the prototype conditions may yield considerably greater values than time to peak of the design flood. Therefore, there is a need to estimate the temporal variation of scour depth. An ex...
Temporal variation of clear water scour at cylindrical bridge piers
Yanmaz, Ali Melih (Canadian Science Publishing, 2006-08-01)
Computation of temporal variation of clear water scour is important for the design of bridge pier footings. Previous studies indicated that very long flow duration was needed to achieve equilibrium scouring situations. However, the corresponding durations in the prototype conditions may yield considerably larger values than time-to-peak of the design flood. Therefore, there is a need to estimate the temporal variation of scour depth. This study deals with the development of a new semiempirical method for te...
A three component force transducer for reinforced concrete structural testing
Canbay, Erdem; Tankut, T (Elsevier BV, 2004-01-01)
The design, manufacture and calibration of two special force transducers, capable of measuring the axial force, shear, and bending moment at the base of a structural column are presented. The special force transducers were fabricated to measure the reactions at the base of the exterior columns of a reinforced concrete three-bay, two-story test specimen. The force transducers had the following capacities: 35 kN for axial load, 4 kN for shear, and 3 kN in for bending moment. These values include a safety fact...
A numerical procedure for the nonlinear analysis of reinforced concrete frames with infill walls
Güney, Murat Efe; Polat, Mustafa Uğur; Department of Civil Engineering (2005)
Materially non-linear analysis of reinforced concrete frame structures with infill walls requires appropriate mathematical models to be adopted for the beams and the columns as well as the infill walls. This study presents a mathematical model for frame elements based on a 3D Hermitian beam/column finite element and an equivalent strut model for the infill walls. The spread-of-plasticity approach is employed to model the material nonlinearity of the frame elements. The cross-section of the frame element is ...
A simplified non-linear procedure for buildings with shear walls
TEKELİ, Hamide; Atimtay, Ergin (Thomas Telford Ltd., 2015-01-01)
A simple and easily applicable analytical method is proposed to obtain the capacity curve of buildings with shear walls as the first stage of a seismic pushover analysis. The method is based on controlling the curvature distribution of shear walls. Accuracy of the method was examined based on data of three sample buildings compiled from the literature. The buildings have different floor areas, number of storeys and cross-sectional areas of shear walls. The method can be economically used with respect to bot...
