Каркасные сооружения благодаря своей экономичности и скорости возведения широко используются в современном строительстве. Для обеспечения их долговечной и безопасной эксплуатации уже при проектировании нужно учитывать негативные последствия аварийных ситуаций, таких как неравномерная осадка фундамента или случайные динамические воздействия. Это позволит заблаговременно принять необходимые меры по усилению конструкций.</p><p>Цель работы – повышение достоверности оценки дополнительных усилий, действующих в элементах каркасного сооружения при неравномерной осадке его фундамента или динамическом воздействии.</p></sec><sec><title>Методы</title><p>Методы.
