In this archive are defined the sections that constitute the structure of the bulkhead (piles or diaphragms). The environment through which it is possible to mange the sections archive is the following:
Environment for the management of the sections
Through this window you can make many operations on sections. You can add or delete sections (using the "+" and "-" in the central upper part of the window). For the correct definition of a section you must enter the following data:
Section: defines the type of the section to add to the archive. You can choose from the following options:
oCircular bars - circular cross section with radially spread reinforcements consisting of classic steel bars.
Model of the section Circular bars
For this category of sections the data to be inserted, in addition to data related reinforcements, managed in the Reinforcements options, is as follows:
▪Name - name of the section
▪Concrete - select from the materials in Materials archive
▪Steel - select from the materials in Materials archive
▪Diameter - expressed in [m]
▪Arrangement (single row, double row, quincunx)
▪Interaxis in 2 directions (the second direction is required only if the arrangement is quincunx) - expressed in [m]
oCircular tubular - hollow section, whose central part is formed by a profiled steel with tubular circular section:
Model of the section Circular tubular
For this category of sections the data to be inserted, in addition to data related reinforcements, managed in the Reinforcements options, is as follows:
▪Name - name of the section
▪Concrete - select from the materials in Materials archive
▪Steel - select from the materials in Materials archive
▪Diameter - expressed in [m]
▪Arrangement (single row, double row, quincunx)
▪Interaxis in 2 directions (the second direction is required only if the arrangement is quincunx) - expressed in [m]
▪Reinforcement: details regarding steel profile (diameter, thickness of the tube - expressed in mm)
oCircular HE shape - hollow section, whose central part is formed by a profiled steel of HE type:
Model of section Circular HE shape
For this category of sections the data to be inserted, in addition to data related reinforcements, managed in the Reinforcements options, is as follows:
▪Name - name of the section
▪Concrete - select from the materials in Materials archive
▪Steel - select from the materials in Materials archive
▪Diameter - expressed in [m]
▪Arrangement (single row, double row, quincunx)
▪Interaxis in 2 directions (the second direction is required only if the arrangement is quincunx) - expressed in [m]
▪Reinforcement: details regarding steel profile (base, height, thickness of the central part (Sa), thickness of wings (Se) - in [mm])
oCircular box shape - hollow section, whose central part is formed by a profiled steel having a rectangular box section:
Model of section Circular box shape
For this category of sections the data to be inserted, in addition to data related reinforcements, managed in the Reinforcements options, is as follows:
▪Name - name of the section
▪Concrete - select from the materials in Materials archive
▪Steel - select from the materials in Materials archive
▪Diameter - expressed in [m]
▪Arrangement (single row, double row, quincunx)
▪Interaxis in 2 directions (the second direction is required only if the arrangement is quincunx) - expressed in [m]
▪Reinforcement: details regarding steel profile (base, height, thickness - in [mm])
oRectangular - rectangular section in reinforced concrete:
Model of section Rectangular
For this category of sections the data to be inserted, in addition to data related reinforcements, managed in the Reinforcements options, is as follows:
▪Name - name of the section
▪Concrete - select from the materials in Materials archive
▪Steel - select from the materials in Materials archive
▪Arrangement (single row, double row, quincunx)
▪Interaxis in 2 directions (the second direction is required only if the arrangement is quincunx) - expressed in [m]
▪Section base (Bx)
▪Section height (Hz)
oInput A, E, I, G - generic section for which must be inserted:
▪Description
▪Area
▪Moment of inertia
▪Modulus of elasticity
▪Shear modulus
For all types of sections is necessary to define the alignment of the reference system. This is the location that the general section should take in the context of structural bulkhead.
For all sections (excluding the generic one) will be calculated the area, moment of inertia and modulus of elasticity.
N.B. The reference system of coordinates is such that the z-axis coincides with the vertical direction, the x-axis with the horizontal axis in drawing plan and y-axis orthogonal to both. From this derives the name Bx and Hz for the geometric data of the rectangular section.
