Intro – validation of Diamonds

The Diamonds results were extensively tested. The table of contents at the bottom of this article provides an overview of all tests already published. The list will expand in the future.

Each test consists of:

• a description of the test
• the results of an independent source against which the Diamonds results were compared
• the Diamonds results
• the difference expressed in percent:

   

• a reference to the independent source

To organize the tests, each test is proceeded by a code according to the following principle:

• For analysis

Type of analysis		Type of bahaviour		Type of model		No.
Static	S	Linear	L	Discrete	D	01 to …
Dynamic	D	Non-linear	N	Linear	L
Thermal	T			Surface	S
				Assembly	X

• For loads

Scope		Type of load		Norm	No.
Loads	L	Snow	S	Eurocode AISC …	01 to …
		Wind	W

• For design

Scope		Type of material		Norm	No.
Design	D	Carbon steel	S	Eurocode AISC …	01 to …
		Stainless Steel	X
		Concrete	C
