Most of the time we design the dynamic foundation with static part ratio less than 0.5 so the cap concrete lower strength should not be a problem as long as the dynamic part is not affected.
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 …

Dynamic foundation design – an integral element of a vibration mitigation strategy. Lower maintenance costs and improved safety –properly designed foundations reduce stresses on bearings. Reduced failure of auxiliary equipment including small-bore attachments . Examples of foundation design and dynamic analysis.

Design of a Foundation Under Vibrating Equipment Abstract. The analysis and design of foundations and structures subjected to dynamic loads from vibrating rotating machines is considered a very complex problem because of the interaction of structural engineering, geotechnical engineering, and the theory of vibration.
An initial assessment may include review of the foundation system design, equipment data and a visual observation with the equipment running. If a full condition assessment is required, STRUCTURAL TECHNOLOGIES performs a series of advanced testing to determine the condition of the foundation system. ... Foundation Vibration Analysis Designed to ...
Foundations for Vibrating Machines. 1. Trial Sizing of Block Foundation: The bottom of the block foundation should be above the water table, wherever possible. In addition, block foundation should not rest on backfilled soil or on soil sensitive to vibration.
foundations subjected to vibratory loads. The design of a machine foundation is generally made by idealizing the foundation- soil system as spring-mass –dashpot model having one or two degrees of freedom. Most machine foundations are treated as surface footing and the soil spring and damping values are determined using
Design Services Foundation Design The function of a foundation is not only to support the weight of the machine/equipment, but also to keep the vibration levels and dynamic displacement of the isolation system within acceptable limits. Designing foundations supporting machines that can produce static and dynamic loads requires sound
Foundations Subjected to Vibration Loads. A practical design tool for sizing equipment mats. The structural design of a foundation system supporting dynamic equipment is complicated by the need to model the periodic load, foundation, and soil conditions; calculate the structural response of the system; and interpret the resulting displacements.
Jan 21, 2019 vibrating machine foundation design recommendation cbailey82 (Structural) (OP) ... A ways back ACI Foundations for Dynamic Equipment was a collection of individual papers. Some pretty much began and ended with the foundation weight should be X times the equipment weight.
Whenever the machine vibrates, soil below the machine foundation also vibrates. The mass of soil which vibrates due to machine vibration is termed as in-phase soil mass. Therefore, total mass (m) is equal to m = m f + m s Where, m f = mass of the foundation m s = in-phase soil mass = it varies from 0 to m f Total mass (m) varies from m f to 2m f. Stiffness (k)
