CRACK RESISTANCE OF JOINT ZONES OF MULTI-LOADED WALLS OF MULTI-STORY STONE BUILDINGS

CRACK RESISTANCE OF JOINT ZONES OF MULTI-LOADED WALLS OF MULTI-STORY STONE BUILDINGS

Abstract

The article presents a comparative analysis of the requirements for ensuring crack resistance of masonry in the junction zone of differently deformable walls of multi-story masonry buildings, which are set out in the currently valid standards for the design of masonry and reinforced masonry structures in the Republic of Belarus and the Russian Federation, and the results of individual studies on this issue. The absence of a methodology for calculating (assessing) crack resistance of masonry in the junction zone of such walls in the new domestic standards is noted. At the same time, such a methodology was present in the cancelled standards. It is also present in the standards of the Russian Federation, which updated the previous standards for masonry structures. Such a calculation methodology was developed on the basis of previously conducted extensive studies. Their analysis shows that in the junction zone of differently deformable walls (due to their different loads and differences in the deformation properties of materials), a complex multifactor stress-strain state is created, which is difficult to express in the form of calculation formulas. Therefore, a simplified calculation method mentioned above was developed to assess crack resistance. It has proven its effectiveness, usefulness and necessity. This calculation method is recommended for use in the design of multi-story stone buildings with its adjustment, taking into account the realities of new standards for stone structures. In this case, the calculation should be accompanied by appropriate design measures, both specified in the standards and in the recommendations based on the results of studies. В статье представлен сравнительный анализ требований по обеспечению трещиностойкости кладки в зоне стыка разнодеформируемых стен многоэтажных каменных зданий, которые изложены в действующих в настоящее время нормах по проектированию каменных и армокаменных конструкций в Республике Беларусь и в Российской Федерации, и результаты отдельных исследований по данной проблеме. Отмечено отсутствие методики расчета (оценки) трещиностойкости кладки в зоне стыка таких стен в новых отечественных нормах. Вместе с тем, в отмененных нормах такая методика присутствовала. Она присутствует и в нормах Российской Федерации, актуализировавшей прежние нормы по каменным конструкциям. Такая методика расчета сложилась на основании проведенных ранее обширных исследований. Анализ их свидетельствует, что в зоне стыка разнодеформируемых стен (вследствие разной их загруженности и различия деформативных свойств материалов) создается сложное многофакторное напряженно-деформированное состояние, выразить которое в виде расчетных формул затруднительно. Поэтому для оценки трещиностойкости и была разработана упрощенная методика расчета, упоминаемая выше. Она показала свою эффективность, полезность и необходимость. Такая методика расчета рекомендуется для использования при проектировании многоэтажных каменных зданий с ее корректировкой, учитывающей реалии новых норм по каменным конструкциям. При этом расчет должен сопровождаться соответствующими конструктивными мероприятиями как оговоренными в нормах, так и в рекомендациях по результатам исследований.
