As of early 2018, CEATI was attempting to form a study group on Vibratory Caisson Design. iii. Structural Design of Foundation The manufacturer was asked to design the caisson's moment capacity to match the loads calculated based on the foundation analysis, which included the maximum moment below scour depth as well as above it.
In the "Large Pump" worksheet, the assumed dynamic analysis of a machine foundation supported on soil is made by the commonly accepted approach of idealizing the foundation-soil system as a simple lumped-parameter, mass-spring-dashpot vibrating system. The "block-type" foundation is assumed to be a rigid body vibrating on the surface of an ...

Aug 15, 2017· Structural Damage from Adjacent Construction Projects – Expert Article. Construction projects in urban and other congested environments frequently require deep excavations and/or the use of heavy vibrating equipment in close proximity to existing structures. These activities require careful planning and engineering in order to prevent damage ...

Foundations for Vibrating Machine Structural Design; Rule of Thumb Report by: Dr. AbdulMuttalib I. Said Ali A. Abdulhameed Professor, Department of Civil Engineering Lecturer, Department of Engineering Affairs University of Baghdad University of Baghdad Background Rules of thumb are numerical values and suggestions that are reasonable to assume based on experience.
The power industry uses a large amount of vibrating equipment, located in multiple geographical areas with differing soil conditions and seismic activity. On some projects, large compressors or turbines are installed within module structures, making the dynamic and seismic design complex and challenging.
The planning of vibratory compaction requires geotechnical competence and careful planning on the part of the design engineer. Similarly, the contractor needs to possess experience and suitable equipment to carry out deep soil compaction. It is common practice to award soil compaction projects to the lowest bidder. However, after
FOUNDATIONS FOR DYNAMIC EQUIPMENT 351.3R-3 f i1, f i2 = dimensionless stiffness and damping functions for the i-th direction, piles f m = frequency of motion, Hz f n = system natural frequency (cycles per second) f o = operating speed, rpm G = dynamic shear modulus of the soil G ave = the average value of shear modulus of the soil over the pile length G c = the average value of shear modulus ...
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
In foundation thicker than 4 ft (1.2m), the minimum reinforcing steel is used (ACI207.2R), or a minimum reinforcing of 3.1 lb/ft 3 (50 kg/m 3 or 0.64%) for piers and 1.91 lb/ft 3 (30 kg/m 3 or 0.38%) foundation slabs. For compressor blocks, 1% reinforcing by volume. For dynamic foundation…
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 …
4) The foundation should be protected from machine oil by means of suitable chemical treatment, which is acid-resistant. 5) Machine foundations should be taken to a level lower than the level of foundations of adjoining structures. [3] 2.1 Design Approach for Machine Foundation The task for designing of foundations for machines with dynamic ...
The following LRFD load combinations are suggested for the design of residential concrete foundation walls: 1.2 D + 1.6 H; 1.2 D + 1.6 H + 1.6 L + 0.5 (Lr or S) 1.2 D + 1.6 H + 1.6 (Lr or S) + 0.5 L; In light-frame homes, the first load combination typically governs foundation wall design.
Chapter 3 - Static Equipment Foundation Design. Pages . 75-134. Abstract. In general, the equipment in oil and gas plants consists of two categories: the static equipment and the rotating equipment. In this chapter, we will focus on the static equipment such as the separator vertical or horizontal, the knockout drum, the vertical desalination ...
approach is to conduct a Structural Vibration Analysis of specific areas of the deck or platform. During the design phase it is easy to make minor changes to the beam orientation and design to avoid resonance. This dynamic analysis is coordinated with the vibration design of large reciprocating and rotating equipment.
