Section Manager 





Calculate the transformed section properties reflecting tendon and reinforcement. Input of reinforcement for the PSC / Composite SteelI / Composite SteelBox Sections becomes more userfriendly. Stress points can be defined at any position for various crosssections. 







From the Main Menu Select Properties > Section > Section Manager. 





Stiffness Transformed section properties with tendon and reinforcement reflected can be calculated for the various section types (DB, PSC, Tapered Section, Composite Section, General and Composite General Section). Transformed section properties can be calculated at the various locations (1/4, 2/4, 3/4 Part) of the Section. The placement of tendon and reinforcement can be viewed. The existing two menus, which are ’r;Section Stiffness Scale Factor’ and ’r;Cross Section Viewer’, have been integrated. Target Section & Element The Elements are displayed under the assigned Section in the Tree. Note Select an Element to input tendon information at an arbitrary location of the Element.
Part Select the position (i, 1/4, 2/4, 3/4, or j) for which the cross section data of the element is to be produced. Once the selection is made, the cross section view at that position is updated. In addition, the reinforcement and the tendon at that position is updated to the View and the Table.
View Point Select the direction based on which the cross section data of the element is to be produced.
Tendon Display the tendon in the View. Property Name : Display the Tendon Property Name in the View. Duct Hall : Display the Duct Hall in the View.
Reinforcement Bar Display the Reinforcement Bar in the View.
Stiffness Scale Factor Boundary Group : Select a boundary group in which the section stiffness scale factor is to be included. Scale Factor(I, J) : Enter the scale factor for each stiffness component. I = J : This becomes active only when the selected section is a tapered section and different section scale factors can be applied to Iend and Jend. Before : Valid for a composite section. The defined scale factors will be used for the calculation of member forces and stresses for the precomposite section. After : Valid for a composite section. The defined scale factors will be used for the calculation of member forces and stresses for the postcomposite section. All : If both Before and After are checked on, the defined scale factors will be used for the calculation of member forces and stresses for the pre and postcomposite sections. Note If Es/Ec (Long Term) and Es/Ec (Shrinkage) are defined in the Section Data, Boundary Groups for the Long Term and the Shrinkage are automatically generated and the applied scale factors are displayed as well. Area : Cross sectional area Asy : Effective Shear Area resisting shear forces in the element local yaxis Asz : Effective Shear Area resisting shear forces in the element local zaxis Ixx : Torsional Resistance about the element local xaxis Iyy : Area Moment of Inertia about the element local yaxis Izz : Area Moment of Inertia about the element local zaxis Weight : Weight density used for calculating selfweight
Coordinate Centroid : Display the locations of tendon and reinforcement with reference to the Centroid of the section.
LeftBottom : Display the locations of tendon and reinforcement with reference to the LeftBottom.
Show Stiffness Display the stiffness with Scale Factor, Reinforcement and Tendon taken into account.
Reinforcement Longitudinal Reinforcement can be input in various ways (Point /Line/Arc/Circle/Poly Line Types can be input in the Grid). The way of inputting Reinforced Shear became convenient.
Target Section & Element Display the Target Section about which the reinforcement data is to be produced in the Tree.
Longitudinal Reinforcement tab Both end part(i, j) have the same reinforcement : Check the box if the reinforcement is identical for both i and j ends of an element. If this option is unchecked, different reinforcement data can be entered under each I and J tab.
Coordinate Centroid : When Centroid is selected, the Centroid becomes ( 0, 0 ). LeftBottom : When LeftBottom is selected, the LeftBottom becomes ( 0, 0 ).
Guide Line If the value is entered, guide lines are generated using the entered spacing relative to the inner and outer lines of the section.
Type There are five ways of entering Reinforcements (Point, Line, Arc, Circle, Poly line). Point Type Center Point (y,z) : Location of the reinforcement Dia : Diameter of the rebar Line Type Input Method A Ref. Y, Y : Reference point in element local ydirection. Distance can be entered from the centroid or left most position. Ref. Z, Z : Reference point in element local zdirection. Distance can be entered from the top or bottom fiber of a section. Num: Number of rebars Dia : Diameter of the rebar Input Method B Starting Point(y,z) : Starting point of the reinforcements End Point (y,z) : End point of the reinforcements Num : Number of rebars CTC : Spacing of rebars Edge Bar : Specify whether to place the rebar at the edge or not Spacing : Spacing of rebars Dia : Diameter of the rebar Arc Type Starting Point(y,z) : Starting point of the reinforcements Passage Point(y,z) : Intermediate point of the reinforcements (1 point) End Point (y,z) : End point of the reinforcements Num : Number of rebars CTC : Spacing of rebars Edge Bar : Specify whether to place the rebar at the edge or not Dia : Diameter of the rebar Circle Type Center Point(y,z) : Center point of the reinforcements Radius : Radius of the reinforcements Num : Number of rebars CTC : Spacing of rebars Dia : Diameter of the rebar Poly Line Starting Point(y,z) : Starting point of the reinforcements Passage Point(y,z) : Intermediate point of the reinforcements (n points) End Point (y,z) : End point of the reinforcements Num : Number of rebars CTC : Spacing of rebars Edge Bar : Specify whether to place the rebar at the edge or not. Reference Select the Reference to locate the reinforcement within a section. Ref.Y : Reference in the Y axis (Left, Centroid, Right) Ref.Z : Reference in the Z axis (Top, Centroid, Bottom) Ref.Point : Reference point for entering CTC (Start, Center, End) Part : Part becomes active only when the section is the Composite Type. In case of Composite Steel I and Composite Steel Box, reinforcement can be placed only at Part 2. As : Total area of the reinforcement that are entered into the Section Concete Contribution factor(or CCF) This factor takes into account some contribution of cracked concrete to the section stiffness by the equation Er x Ar / CCF. Er : Modulus of elasticity of reinforcement Ar : Area of reinforcement in the slab CCF=1 means that cracked concrete contributes nothing. Only the area of reinforcement in the slab will be considered to calculate section properties of cracked section. CCF=0.5 means that cracked concrete contributes in some amount. The area of reinforcement in the slab will be double to calculate section properties of cracked section.
Reinforced Shear tab Both end part(i, j) have the same reinforcement : Check the box if the reinforcement is identical for both i and j ends of an element. If this option is unchecked, different reinforcement data can be entered under each I and J tab. Diagonal Reinforcement : Inclined shear reinforcement Pitch : Interval of the inclined shear reinforcement Angle : Angle of inclination for the shear reinforcement Aw : Total area of inclined shear reinforcing steel Steel Bar for Web : Shear steel bar Pitch : interval of shear steel bars Angle : angle of inclination of shear steel bars Ap : total area of shear steel bars in webs Pe : effective prestress of the total shear steel bars in webs Shear Reduction Factor : reduction factor for effective prestress Torsional Reinforcement : transverse torsional reinforcement Pitch : interval of transverse torsional reinforcement Awt : total area of transverse torsional reinforcing steel Alt : total area of longitudinal torsional reinforcing steel Enclosing Stirrup : Input the data needed to calculate the enclosed section area used for the calculation of torsional moment Cover Thickness : cover thickness of the enclosed stirrup Include Flange/Cantilever : Check on when the Itype section flange and the cantilever part of Box type section is included in the Cover Thickness. Area of Reinforcement The area of reinforcement can be entered using the ’r;Area of Reinforcement’ dialog box.
Stress Points Stress Points can be defined at any position for the section types of DB, PSC / PSC Value, Tapered Section, Composite Section, General and Composite General Section. Stress Points can be defined at Part2 of the Composite Section. Coordinate Centroid : When Centroid is selected, the Centroid becomes ( 0, 0 ). LeftBottom : When LeftBottom is selected, the LeftBottom becomes ( 0, 0 ).
Stress Point Stress Check Points of the section are displayed. (Read Only) Note For the PSC Type, ten Stress Check Points (including Shear Check Points Z1, Z2, and Z3) are displayed. For other types, four Stress Check Points are displayed.
Additional Stress Point Additional Stress Points can be added up to ’r;n’. When Additional Stress Points are added, edited or deleted from the Table, they are updated in the View in real time.
