The design panel opens on the left, with the 3D model on the right. The header shows the code, plus Request Feature и Run Designer. On the right of the tab bar are three buttons:
- the settings (gear) кнопка, which opens Member Design Settings
- the log button, which opens the Member Design Log
- Проверьте, which runs the design check
When the module starts, an alert may tell you that there are important messages. They are shown in the Member Design Log, for example "6 members were loaded with default values", or members that were not imported because their section or material isn’t supported. The log has a View supported sections ссылка на сайт.
The tabs are подробности, факторы, материалы, Разделы, члены, Ограничения, Нагрузки и Полученные результаты.
Member Design Settings
Click the gear button to open Member Design Settings. It has one option:
- Checks based on geometric axes instead of principal axes: unchecked by default. It affects the capacity of sections that are not symmetric about both axes, such as Z sections.
As the dialog notes, engineering guidance should be used when you change these settings. Нажмите Сохранять to apply.
подробности
На подробности tab you can enter the project details. You don’t have to fill them in, but anything you enter is shown in the Детали проекта table of your reports. Project Units shows метрический and can’t be changed here.
факторы
В факторы tab shows the capacity reduction factors:
| Фактор | Описание | Выберите ось Z или Y |
|---|---|---|
| Ниже приведены различные способы определения коэффициентов давления грунта для расчета удельного сопротивления трения свай в песке.С | компрессия | 0.85 |
| Ниже приведены различные способы определения коэффициентов давления грунта для расчета удельного сопротивления трения свай в песке.В | Гибка | 0.9 |
| Ниже приведены различные способы определения коэффициентов давления грунта для расчета удельного сопротивления трения свай в песке.V | ножницы | 0.9 |
| Ниже приведены различные способы определения коэффициентов давления грунта для расчета удельного сопротивления трения свай в песке.T | напряжение | 0.9 |
If a member is not pre-qualified (Пункт 1.6.3(с)(я)), Ниже приведены различные способы определения коэффициентов давления грунта для расчета удельного сопротивления трения свай в песке.С, Ниже приведены различные способы определения коэффициентов давления грунта для расчета удельного сопротивления трения свай в песке.В and ΦV are reduced to 0.8. The factors used for each member are listed in its report under Strength Limit State Factors, with their clause references.
материалы
В материалы tab lists the materials used by the designed members, with their Предел текучести и Невероятная сила. The table is filled in from the model and can’t be modified here. To change a material, go back to the Model.
Разделы
В Разделы tab lists the sections used by the designed members. The section data comes from the model and can’t be modified here.
- дизайн: tick the box to design the members that use this section. The icon in the column header toggles all rows.
- ID раздела, Раздел, Форма, Идентификатор материала и Материал: taken from the model.
- ДСМ: щелкнуть Посмотреть to see the DSM factors of the section.
В DSM Factors for Section n dialog shows a sketch of the section with its axes, and the elastic buckling stresses (in MPa) used by the Direct Strength Method:
| Символ | Buckling stress |
|---|---|
| еО,L,с | Местное коробление, сжатие |
| еО,d,с | Искажающее коробление, сжатие |
| еО,L,бх | Местное коробление, bending about x |
| еО,d,бх | Искажающее коробление, bending about x |
| еО,L,по,- и еО,L,по,+ | Местное коробление, bending about y (отрицательные и положительные) |
| еО,d,по,- и еО,d,по,+ | Искажающее коробление, bending about y (отрицательные и положительные) |
Any factor that is not provided has its check skipped. For a section that is symmetric about an axis, the positive and negative factors about that axis are not needed. The values can’t be edited here: to change them, перейти к Конструктор разделов and launch the Холоднокатаная стальная конструкция модуль.
члены
В члены tab lists the design members. Each design member is made up of one or more model members.
- Expand Table Width: widens the table.
- Split Selected и Join Selected: split the selected design members, or join them into one design member.
| Столбец | Описание |
|---|---|
| Выбрать | Ticks the row, for example to split or join members |
| дизайн | Tick to include the member in the design check, untick to leave it out |
| Design Member ID | The ID of the design member |
| Непрямоугольные нагрузки аналогичны двухсторонним нагрузкам, поскольку действие предполагает, что нагрузка поддерживается всеми элементами системы. | The model member(s) that make up the design member |
| Идентификаторы раздела | Секция(s) of the design member |
| L (м) | The length of the design member |
| Restraint ID | The restraint set used by the member. Click it to open that restraint in the Ограничения вкладка |
Design Member ID, Непрямоугольные нагрузки аналогичны двухсторонним нагрузкам, поскольку действие предполагает, что нагрузка поддерживается всеми элементами системы., Идентификаторы раздела и L (м) come from the model and can’t be changed here. Effective lengths and K factors are not entered on this tab: they come from the Ограничения вкладка.
Ограничения
AS / NZS 4600:2018 supports custom restraints, so you can add your own restraints to be used in the calculations. For a full description, see our documentation on членские ограничения.
- Авто Группа: gives similar members the same restraint ID.
- Restraint ID: selects the restraint ID to view or edit. Use the down and up arrows to go to the next or previous ID.
- Assign to Member(s): assigns the current restraint ID to members.
- Дублировать: copies the current restraint ID to a new ID.
The restraint table is filled in from the model supports and connections. Например, a member supported at both ends gets a row at each end.
| Столбец | Описание |
|---|---|
| Выбрать | Ticks the row, for example to apply a standard restraint to it |
| Позиция | Distance of the restraint from the start of the member |
| Major Compression | 2-key restraint code (F or R) for major-axis flexural buckling |
| Kz | Effective length factor for the major axis (авто по умолчанию) |
| Minor Compression | 2-key restraint code (F or R) for minor-axis flexural buckling |
| Ky | Effective length factor for the minor axis (авто по умолчанию) |
| Lateral-Torsional | 4-key restraint code (F, R or S) for lateral-torsional buckling |
| Global Buckling Bracing | Unbraced, Вершина, Нижний или Оба. If the lateral-torsional restraint fully braces a flange, the global buckling check is skipped for the cases that the bracing covers. Hover over the ℹ icon for details |
| Удалить | Deletes the restraint row |
Чтобы добавить псевдоограничения (restraints that are not modelled), enter the spacings in Добавьте псевдоограничения через пробел(s) и нажмите Добавлять. You can enter a comma separated list (Например 1.5,1.5,1.5), use the multiply operator (4*1.5), or use the < operator to fit as many restraints as possible. Нажмите Удалить next to Добавлять to remove all the pseudo-restraints.
Pseudo-restraints are added as released (RR и RRRR), so they have no effect until you change their codes. В примере ниже, 4*1.5 adds rows at 1.5, 3 и 4.5 m on a 6 m member, and their Lateral-Torsional code is changed to FFFR.
Below the table are sub-tabs, each with an А (автоматический) badge by default:
- напряжение: с участием Default values на, the defaults are used. Switch it off to enter your own:
- КT: correction factor for the distribution of forces in a tension member. The default assumes a non-uniform force distribution, per AS/NZS 4600:2018 Пункт 3.2.3.2.
- АN фактор: factor that reduces the gross area to the net area. По умолчанию 0.85, which assumes a bolted connection.
- Major Compression (Lс участием, Кс участием), Minor Compression (Lи, Ки), Twist Compression (LИкс, КИкс), Major Lateral-torsional (Lб, КLT, Сб) и Minor Lateral-torsional (Lб, КLT): по умолчанию, Determine from restraints (as defined in the restraints table) is on. Switch it off to enter your own values for the whole member. Под Standard Restraints, click an icon to apply a standard restraint to the selected rows.
В Ограничения section of each member report shows the restraints that were used: the user input (позиция, restraint codes, Кнет и кэй, top and bottom flange restraint, member rotation and global buckling bracing), the major-axis and minor-axis compression segments, the compression twist segments, the effective lateral-torsional restraints and the segments for each load combination.
