Design of Pinned Column Base Plates

January 15, 2009 · 1 Comment

design-pinned-column

This paper is one of a planned series which deals with the design and use of rationalized structural connections. It draws heavily on the excellent work done in the publication “Design of Structural Connections” by Tim Hogan and Ian Thomas. Since that time, there has been new research, some variations to the design models, new steel grades introduced and some minor changes in section properties. We have also seen the adoption of sophisticated 3D modeling software which has the capability to generate many different connection types. The ASI, through this project is endeavouring to provide an industry wide rationalized set of dimensions, models and design capacities.

TURBO GENERATOR MACHINE FOUNDATIONS SUBJECTED TO EARTHQUAKE LOADINGS

January 14, 2009 · Leave a Comment

turbo-generator

For industrial partners, actual simplified design rules in line with the growth of knowledge regarding earthquake engineering are essential for competitiveness. As turbo generators are placed all over the world, i.e. in different seismic hazard zones, not only machine sets but also the foundations have to be standardised and able to resist certain earthquake loading levels. Prior to the release of new or revised turbo generators (foundations), extensive static and dynamic calculations are carried out to confirm the foundation outline and basic dimensions, and also verifying the resistance against unfavourable load combinations. Based on gained knowledge of detailed seismic analyses, practical design approaches have been elaborated for different kind of foundation types (mainly spring mounted, table mounted and raft foundations); and, for some machine manufacturers, summarised in specific design criteria.

Design of Machine Foundation on Reinforced Sand

design-of-machine-foundation

Dynamic analysis to evaluate the response of earth structures to dynamic stress applications, such as those produced by earthquakes, blasting, wind loading or machine vibrations are finding increased application in civil engineering practice. In the present investigation the authors have calculated the dynamic soil parameters, the coefficient of elastic uniform compression (Cu), coefficient of elastic uniform shear (Cτ), coefficient of elastic non-uniform compression(Cφ) and coefficient of elastic non-uniform shear(Cψ) by performing laboratory model cyclic tests on annular footing resting on un-reinforced and reinforced earth beds.
