8B. ANALYSIS PART 2

CHAPTER 8B 'ANALYSIS' 130 This diagram is based on the following assumptions: The calculation of the moment My is based on relation (A.6) of Annex 7A of CEE/CNR. • The value of My is different for each step, due to the axonal input in its calculation. In the skeletons of the members of the masonry and in the skeletons for concrete members the skeleton is calculated with the axial of each step. • Two values of My (positive and negative) are calculated and two regions with (different) boundaries for the performance levels are drawn respectively. For poles, due to the existence of symmetrical reinforcement, the two values will always be the same. As is known, the diagram does not have an elastic branch and only shows the corresponding plastic region. • The values of θ have been divided by the corresponding safety factors. The limits θpl corresponding to the performance levels have been divided by the coefficient γrd=1.8 and the turning angles θsd have been multiplied by the factor γsd.
