Arrangement of Risky Building Analysis Settings 6. Risky Building Analysis Reports Arranging existing building materials Performance in the program You can determine the concrete compressive strength and steel class of the building you will analyze from the materials folder in the building tree. To define the existing reinforced concrete material; -> Open the Materials folder in the Structural Tree view. -> To interfere with the existing material, press the right mouse button on the material and click on the Properties line from the pop-up menu. -> Static Material Properties dialog will open. -> Edit the concrete characteristic compressive strength and reinforcement yield stresses according to your current project data. By default, 20 will appear in the concrete characteristic compressive strength line. This value defines the C20 class as concrete. If necessary, make another selection from the list, or if you have a non-list value, type that value. Concrete characteristic tensile strength, constant k1, elasticity and shear modules will change automatically according to the concrete type you choose. Select the reinforcement class in the Bending reinforcement yield stress line. For example, the value 420 defines the class S420. If necessary, make another selection from the list, or if you have a non-list value, type that value. Creating the building model: The method to be followed in modeling the building is the same as creating a new building model. There may be issues that need to be changed on the basis of structural elements. These issues are explained in order below: Columns You can adjust the status of stirrup arrangements of your existing columns by interfering with the Stirrup tightening available lines in the Column Settings/Performance Analysis tab. If there is stirrup tightening in the column in question belonging to the structure under investigation, with 135 degree hooks, the option is marked. Otherwise it is not marked. Curtains You can adjust the status of stirrup arrangements of your existing curtains by interfering with the Stirrup density available lines in the Curtain Settings/Performance Analysis tab. If there is stirrup tightening on the aforementioned curtain of the structure under investigation, with a hook of 135 degrees, the option is marked. Otherwise it is not marked. Arranging the reinforcement Another issue that needs to be adjusted before the risk assessment of your building is the definition of the reinforcements to the program as applied on site. For this, you can intervene in the reinforcements of the relevant elements from the dialogs under the Reinforced Concrete menu. In addition, by using the purchase lines in the Risky Building Analysis dialog, you can make a calculation taking into account the presence of the reinforcement in the sections at the ratios you specify, without entering data into the reinforced concrete menus. Existing purchases can be given during the Risky Building Analysis. Arrangement of beam reinforcement: -> Click on the Reinforced Concrete/Beam line. -> Click the Beams tab in the dialog that opens. -> If you click the All Floors box at the bottom of the dialog, you can view all your beams at once. -> In this dialog, arrange the beam reinforcements according to your current structure. Arrangement of column reinforcements: -> Click on the Reinforced Concrete/Column line. -> Click the Columns tab in the dialog that opens. -> If you click the All Floors box at the bottom of the dialog, you can view all your columns at once. -> In this dialog, arrange the column reinforcements according to your current structure. Arrangement of curtain reinforcement: -> Click on Reinforced Concrete/Shearing line. -> Click the Curtains tab in the dialog that opens. -> If you click the All Floors box at the bottom of the dialog, you can view all your curtains at once. -> In this dialog, edit the curtain reinforcements according to your current structure. Fixing the edited rebars: Another issue to be considered while arranging the rebars is that the DS column in the dialogs is checked after arranging the rebars. If this column is not checked, it means that the reinforcement entered in the relevant element is not fixed. When you do the analysis in the next step, the reinforcements of these unfixed elements will change according to the end forces found. Analysis After the modeling process of the existing building is completed according to the available data, it is necessary to perform an analysis once in order to define the floor type and to automatically create load combinations in the program. To have an analysis, simply click on the Analysis/Analysis+Reinforced Concrete line. Editing Risky Building Analysis Settings When the risky building analysis button is pressed in the program, the Risky Building Analysis dialog will appear. Analysis type: In risky building analysis, it is selected whether the earthquake load will be determined according to the equivalent earthquake load method or according to the mode combination method. The level of knowledge of the building: It is obtained from Table 1 in the regulation published for the determination of risky buildings. Knowledge level coefficients; Minimum - > 0.90 Comprehensive -> 1.00 Critical floor: It is the floor defined in the scope section of the regulation published for the determination of risky buildings. Select the floor to be considered as critical floor from the list. Consider screed in beams: If checked, the beam's cross-section is considered as a slab cross-section and the reinforcements of the slab in the slab are included in the existing reinforcement areas of the beams. If it is not marked, the cross section of the beam is considered as a rectangular section and the reinforcements of the floor in the table are not included in the existing reinforcement areas of the beams. Increase the beam capacities according to the vertical calculation: If the option is checked, it is assumed that the capacity moments of the beams cannot be less than the capacity moments calculated after the vertical calculation. Consider crossties in column Vr calculation: If checked, crossties in the column are added to the column stirrups and taken into account in column Vr calculation. If it is not checked, it will not be accepted. Defined beam margins: If the option is checked, beam capacity moments are calculated taking into account the given margins. Defined column margins: If the option is checked, column capacity moments are calculated by considering the given margins. Defined panel margins: If the option is checked, the shear capacity moments are calculated by taking into account the given fractional values. Risky Building Analysis Reports After performing the performance analysis in the program, the Risky Building Analysis Report will be automatically displayed on the screen. Detailed risk assessments of the elements in the critical floor and the floor with the largest relative displacement are printed in the report.
