B. COLUMN REINFORCEMENT DETAILS

64 CHAPTER B: COLUMN REINFORCEMENT DETAILS • Pressing the "Delete" button deletes the lamina or IOP of the selected pole and recalculates the interaction diagrams. OBSERVATION You need to re-adjust the thickness of the tyres based on the minimum t1 and t2 and redo the checks. But because the way of calculating the t2 thickness is an iterative procedure, by selecting the key: The program automatically calculates the final minimum thickness t2 required. But you must still import it and do the final checks. Adequacy of the laminate or EOP is achieved either by increasing the thickness or increasing the number of layers. • In the results section - The checks for the adequacy of bending strength for the whole cross-section and shear strength of the concrete, per direction, based on section (vi) of § 8.2.1.3 (a) of the CEE Code, are shown first. - Then and by side is calculated, i.e. the difference between the design moment and the moment of resistance of the original cross-section and if this difference is positive (which means that reinforcement is required) t1 and t2 are calculated based on the above. The value t is the thickness given by the designer. EXAMPLE In the above example, the thickness t entered is less than the required t1 and t2. t=0.7 must be inserted. However, if the thickness t=0.4 is maintained and 2 layers are inserted, then the results become
