Designing these dynamic foundations requires a series of static and dynamic analyses to meet the vibration requirement of the equipment and any seismic requirements of the local building codes. This article researches and compares different modeling methods, and then proposes an efficient approach for their design in high seismic regions.

In this field project, the foundation was modified. A beam was added under the skid and welded to the existing piles. By adding an extra beam, stiffness was provided midspan to support the equipment above it. If a foundation analysis and design had been completed before construction, a pile would have been installed at that location. Ima g

Foundations and structures supporting vibrating machines require a specific design in order to minimize the negative effects of vibrations. The performance (as well as safety and stability) of machines depend largely on their design, manufacturing and ultimately on the interaction with the environment. Therefore,

Apply the knowledge of analysis and design procedure for equipment foundation design and evaluate vibration damage and take suitable remedial measures. The course considers loads induced by different machinery, modes of structural response of the foundation and/or supporting frame, as well as the response and damping provided by the soils.

Foundations and skids and support the compressor and driver, ensuring frame and coupling alignment and providing energy paths for dissipation of equipment unbalance and other time-variant forces. proper foundation and skid design is a critical success factor when ap-plying high-speed reciprocating compressors in this size range.
Some firms specify a minimum reinforcing of 3.1 lbf/ft3 (50 kg/m3 or 0.64%) for piers (machine support edestals) and 1.9 lbf/ft3 (30 kg/m3 or 0.38%) for foundation slabs. For compressor blocks, some firms suggest 1% reinforcing by volume and may post-tension the block. Appendix - Reinforced Concrete.

tice on grouting. Design practices for foundations supporting static equipment are discussed in ACI 351.2R. There are many technical areas that are common to both dynamic equipment and static equipment foundations. Various aspects of the analysis design and construction of foundations for static equipment are addressed in ACI 351.2R.
Structural Types of Foundations. There are two categories of structural foundation design for buildings in the world of Structural Engineering that you should be aware of: 1. Shallow Foundation. The shallow foundation, as its name implies, is a foundation with a lower depth. The depth of the shallow foundation is usually between 1 and 3 meters ...
The job of a foundation is to transfer the loads of the building safely to the ground. Laying of Column Footing Reinforcement | Foundation Design. The strength of the foundation determines the life of the structure. As we discussed in the earlier article, design of foundation depends on the type of soil, type of structure and its load.

Foundation of dynamic equipment is a bit different from normal foundation since such foundation not only resists the static loads but also dynamic loads from vibrating machine. Vibrating machine could be a compressor, pump, turbine-generator or other equipment with vibrating mechanism.
Eccentricity: For Framed foundation there are two connotations to the term eccentricity: 1. Overall eccentricity: it is defined as the distance between the centre of mass of the over all system ( machine+ foundation) and C.G of …

You will be able to design equipment foundations using hand techniques, common finite element packages as well as specialized software (DYNA 6). Course Outline: Intro to design of equipment foundations Method of dynamic impedance Dynamic soil properties Design of shallow and pile foundations Determination of loads from types of machinery
However, the combination of large foundations and the soil provided the system with a lot of damping. Although the process equipment was identical for all four locations, the foundation design itself could not be a "one-design-fits-all" solution because of varying soil conditions.
