EXAMPLE 11. MASONRY WITH THE EQUAL FRAME METHOD

PARADEIGMA 11: " MASONRY M.I.P." 14 The calculation of the targeted movement is done either by CANEP (method of coefficients) or by EC8. It should be noted that these parameters, because they relate to the calculation of the targeted movement, can be set or modified and after run the inelastic analysis without the need to re-run it. The same applies to the control node. At each step, the incremental load factor λ , defined as the product of of the worst strength (the smallest of the 4 resulting from the 3 in-plane and 1 out-of- plane failure modes) to the corresponding stress magnitude. With the default value of 0 in the Lambda Range (%) parameter, the program selects a minimum value, i.e. only one element, even if there are values from other elements that are very close to it. Setting a value other than 0 e.g. 10% means that those λ values that are less than or equal to the minimum value λ plus 10% will be taken into account in this step with result in more than one plastic joint being created at the same time. Assume that in the first step of the pushover the minimum value λ is 1 and corresponds to a the specific structural element on which the plastic joint will be created. By setting a value of 10% in this parameter, elements with λ values from 1 to 1.1 will also have plastic joints created in them, simultaneously with the first element. The smallest of the 4 strengths is the one that defines the type of failure, the limit of rotation θu and determines the skeletal diagram (different for in-plane and out-of-plane failure).
