in the bridge wizard if i model a box girder i need to determine the d.o.f for bearing for integral substructure and also for foundation spring so as to have correct results at the cap beam of integral substructure also i need to know where exact to assign the bearing location and substructure location i hope to get a ready model (spine frame not shell element ) thx..

Product Description:
Computational fluid dynamics (CFD) techniques are used to study and solve complex fluid flow and heat transfer problems. This comprehensive text ranges from elementary concepts for the beginner to state-of-the-art CFD for the practitioner. It discusses and illustrates the basic principles of finite difference (FD), finite element (FE), and finite volume (FV) methods, with step-by-step hand calculations. Chapters go on to examine structured and unstructured grids, adaptive methods, computing techniques, and parallel processing. Finally, the author describes a variety of practical applications to problems in turbulence, reacting flows and combustion, acoustics, combined mode radiative heat transfer, multiphase flows, electromagnetic fields, and relativistic astrophysical flows. Students and practitioners--particularly in mechanical, aerospace, chemical, and civil engineering--will use this authoritative text to learn about and apply numerical techniques to the solution of fluid dynamics problems.

3D Pushover of Irregular Reinforced Concrete Buildings
ABSTRACT
Seismic response of irregular plan buildings can be assessed by using tyme history analysis: however, this process is, in general, lengthy and has to be repeated many times to have a wide set of results that could represent the performance of the system facing any seismic excitation. Obviously, such procedure may take up considerable time before significant and useful data is obtained in the analysis of an irregular system: therefore, some other procedures, less time consuming and equally reliable, have been developed, one of them is the pushover analysis. Pushover is a tool that is widely used to predicted the strenght and response of 2D frames.
Currently, in this research, the methodology is extended to assess the performance of 3D irregular RC structures. Important issues regarding diaphragm effects, direction of load application, loading profiles and arrangement of the incremental dynamic analysis results have been studied: in addition, the capability of adaptive pushover has ben tried. Two RC irregular buildings and six earthquake ground motions were employed throughout the research. From the processing of the above information preliminary conclusions are drawn and future lines of research are proposed.

Periods of Vibration for Displacement-Based Assessment of RC Buildings
ABSTRACT
Simple empirical relationships area available inmany design codes to relate the height of a building to its fundamental period of vibration. These relationships have been realized for force-based design and so produce conservative estimates of period such that the lateral shear force will be conservatively predicted from an accelaration spectrum. Where assessment of a structure is concerned, it is the displacement demand that gives an indication of the damage that can be expected, this displacement would be underestimated with the use of the afermentioned period-height formulae. Furthermore, the period of vibration of interest in assessment is the yield period, which is calculated using the yield stiffness, also often referred to as the cracked or elastic stiffness.
