Аннотация
Надежность работы конструкций и сооружений в целом в процессе их эксплуатации существенно зависит от многих факторов, не всегда в полной мере учитываемых расчетом. Одной из причин этого может быть узкая направленность многих экспериментальных исследований, результаты которых приняты для ориентации при разработке теории расчета. Иногда теории расчета совсем не обоснованы экспериментальными исследованиями и поэтому могут давать большие расхождения с опытными результатами. Методика проведения экспериментальных исследований окажет положительный эффект на разработку надежной теории расчета изгибаемых железобетонных элементов по наклонным сечениям только тогда, когда будет сочетать все разнообразие влияния основных факторов на работу исследуемых элементов, в том числе и вид приложенных в процессе испытаний нагрузок - равномерно распределенных или сосредоточенных, с глубоким анализом полученных результатов. В предлагаемой теории расчета прочности по наклонным сечениям изгибаемых железобетонных элементов используется взаимосвязь в развитии напряженно-деформированного состояния при действии нагрузки как в нормальных, так и наклонных к продольной оси элементов сечениях, вплоть до разрушения балок, полученная в результате экспериментально-теоретических исследований. Это обеспечивает близкое совпадение опытных и расчетных данных, повышает надежность, долговечность и экономичность конструкций в процессе их эксплуатации.
