У статті розглядається задача параметричної оптимізації металевих стержневих систем, представлена як задача нелінійного програмування зі змінними (невідомими) розмірами поперечних перерізів елементів конструкції, а також зусиллями попереднього напруження, що вводяться у визначені зайві в’язі стержневої системи. Система обмежень охоплює обмеження несучої здатності, що формулюються для усіх розрахункових перерізів несучих елементів конструкції, що підлягає дії усіх розрахункових комбінацій навантажень першої групи граничних станів, а також обмеження переміщень визначених вузлів стержневої системи, що підлягає дії усіх розрахункових комбінацій навантажень другої групи граничних станів. Для розв’язку задачі параметричної оптимізації використовувався метод проекції градієнта функції мети на поверхню активних обмежень з одночасною ліквідацією нев’язок в порушених обмеженнях. Для складних багато раз статично невизначених стержневих систем запропонована чисельна методика визначення оптимальної кількості зайвих в’язей для введення зусиль попереднього напруження.
В статье рассмотрена задача параметрической оптимизации металлических стержневих систем, представленная как задача нелинейного программирования с переменными (неизвестными) размерами поперечных сечений элементов конструкции, а также усилий предварительного напряжения, которые вводяться в определенные лишние связи стержневой системы. Система ограничений охватывает ограничения несущей способности, сформулированные для всех расчетных сечений несущих элементов конструкции, подлежащей действию всех расчетных комбинаций нагрузок первой группы предельных состояний, а также ограничения перемещений определенных узлов стержневой системы, подлежащей действию всех расчетных комбинаций нагрузок второй группы предельных состояний. Для решения задачи параметрической оптимизации использовался метод проекции градиента функции цели на поверхность активных ограничений при одновременной ликвидации нев’язок в нарушенных ограничениях. Для сложных много раз статически неопределенных стержневых систем предложена численная методика определения оптимального количества лишних свіязей для введения усилий предварительного напряжения.
The paper considers parametric optimization problems for the steel bar structures formulated as nonlinear programming ones with variable unknown cross-sectional sizes of the structural members, as well as initial prestressing forces introduced into the specified redundant members of the structure. The system of constraints covers load-bearing capacity constraints for all the design sections of the structural members subjected to all the design load combinations at ultimate limit state, as well as displacement constraints for the specified nodes of the bar system, subjected to all design load combinations at serviceability limit state. The method of the objective function gradient projection onto the active constraints surface with simultaneous correction of the constraints violations has been used to solve the parametric optimization problem. A numerical technique to determine the optimal number of the redundant members to introduce the initial prestressing forces has been offered for high-order statically indeterminate bar structures.
