Equivalent frame analysis

Equivalent frame analysis

RE: Equivalent frame analysis

LMW.dk,

7200mm is the transverse tributary width for the LINE B frame run.

3600mm from span A-B (ie 50% of 7200mm), and similarly, 3600mm from span B-C, for a total of 7200mm panel width.

The 1800mm red lines designate your half column-strips.

Ingenuity already more or less answered your question and within an hour of your original question. If you need help that quickly ask whatever engineer is mentoring you. Otherwise you'll probably have to wait a bit for anyone else to answer. In the meantime I'd read up on equivalent frame analysis and you might just find your answer.

RE: Equivalent frame analysis

It appears that your spans are different;I'd typically run two transverse strips to determine the locations of the Point of Zero Shear (PZS) and use these to determine the tributary widths. You have two strips, one at the core and one elsewhere and use a straight line to connect the two PZS lines. I typically treated slab to core attachment as generally approaching a fixed end condition. Haven't done an equivalent frame for a long while.

The function of a circuit breaker is to provide overload (thermal) and short-circuit (magnetic) protection to a circuit and its downstream components. A circuit breaker functions like an airbag in a car, protecting circuit components and people by tripping the circuit to interrupt the current flow if it detects a fault condition in the control system.

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
