This allows the user to quickly determine if there are any problems in the stack. The program also calculates the natural frequency of the structure so that the dynamic along wind and dynamic across wind vortex loads can be applied to the stack. Standards Subsctiption may be the perfect solution. Design of stacks Aliaga: Such issues are the result of project complexity, size, uniqueness and regulation, as well as the need for virtual team collaboration.
I would typically design the foundation and anchor rods for the building code environmental loads but I’m thinking there may also be vortex shedding loads and loads due to velocity discharge of the stack. Cheaper than making a mistake or two.
Given the fundamental frequencies of the chimney, this structure is assumed as rigid for the purpose of wind assessment and therefore a static analysis was conducted based on the application of equivalent static loads. Some conditions must be met: Step 4 – Define Details A breech opening can be modeled so that the software will automatically consider the reduced strength due to an opening.
Table 4 systematises structural data, namely dimensions, mass and damping ratio defined according to the ASME STS specificationforce coefficients and importance factor. The results of a complementary verification of the sensitivity of the chimney to vortex shedding are summarised in Table 8, following the methodology proposed in the ASME STS specification.
Finally, the response spectrum analysis results based on the first 7 modes and on an SRSS combination are presented in Table 16, and colour maps of the stresses are shown in Figures 9 and 10 for the two chimney conditions, NTNC and TC, considering independently combinations of the seismic forces along X and Y directions with forces along direction Z.
Design response spectrum according to UBC and parameters from Table You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. The user may mix-and-match from the following available codes: Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor.
Should you require references from some of these companies and individuals please let us know. The very high calculated amplitudes of vibration and stresses motivated the option to implement a tuned mass damper TMD tuned to the direction Y most flexible direction.
ASME STS – Steel Stacks
The foundation issues I am familiar with but I may also be asked to design the 201 itself and I would like to get up to speed in the meantime. Step 1 – Design Codes The user would select the appropriate design code for the stack. Resources Few production environments have the luxury of ordering new equipment to replace existing machines on their shop floor.
Are you an Engineering professional? 2011 stack design was based on the following codes: It outlines areas requiring maintenance and inspection following initial operation.

As the voice of the U. However, for the purpose of comparison, the loads determined according to the static force procedure have been calculated and are summarised in Table 13 considering the first two modes in each direction. Standards Subscriptions asmme ANSI provides a money-saving, multi-user solution for accessing standards.
I’d suggest you turn the design over to pros. You may delete a document from your Alert Profile at any time. Step 3 – Define Attachments Now the user defines all of the non-structural attachments on the stack such as ladders, platforms, piping, insulation, and more.
It outlines the consideration that must be asm for both the mechanical and structural design.
Here is a brief outline of the 5 simple steps that are followed to analyze a stack: Please first verify your email before subscribing to alerts. Also the seismic code is selected, and there are several to choose from:
