How to calculate diaphragm R C K?

It can be calculated by means of elastic analysis of the frame. r=c/k is the relative flexibility of the diaphragm respect to the flexibility of the frame. It is an important value as it will be seen the distribution of forces do not depend on the absolute values of c and k if not in the relative flexibility r.

How to determine if a building is stiffened with a diaphragm?

6.1.3.1. The first analysis is to check which is the maximum relative flexibility (r) that can be allowed in the different buildings in order to consider that they are stiffened with the diaphragm. The building has the same portals over the whole length; as a consequence the diaphragm will be effective if all the frames are restrained.

When should a diaphragm actuate?

A third point, maybe the most important, should not be forgotten and it is to check that the diaphragm really actuates as a diaphragm. When the horizontal loads act on the long lateral side of the building (following the direction of the frames).

How can industrial facilities reduce energy and demand costs?

Industrial facilities have tremendous potential to decrease their energy and demand costs through means of ES to shave the peak load off the power grid, bringing greater balance between production and demand, while simultaneously improving the reliability and financial performance of the power grid ( Tronchin et al., 2018 ).

How do I know if a diaphragm has been used?

Specify clearly in the building that the diaphragm have been used: as the stability of the building relies on the roof, and openings reduce the strength and increases the flexibility, it should be clearly marked that the design has been used.

Does a diaphragm absorb lateral force?

building that is too long or a diaphragm that is too flexible will not absorb any force, and consequently the frames (which maybe are not designed for it) will absorb all the lateral force. method to calculate this interaction, and an analysis of the results in different cases realised by the author are provided in the next pages. 6.1.1.
