The impact of light rail transport noise on populated areas
Seismic safety of buildings and structuresThe document describes how the noise level was measured on the facade of a multi-storey residential building in Tashkent. The building has two sides parallel to the railway located about 25 m from it. Because of the short distance the noise level of trains is well above the permissible limit on the facade of the building, the objective of the acoustic study presented in the document was to ensure that the noise level measured at a distance of 2 m from the facade of the building, It was in compliance with the noise insulation standards of Uzbekistan and SP 353.1325800.2017, which fully comply with international standards.

Оценка реакции изолированной суперструктуры на сейсмические воздействияВ настоящее время одним из наиболее перспективных методов активной сейсмозащиты зданий и сооружений является сейсмоизоляция. Сейсмоизоляция является одним из основных способов обеспечения сейсмостойкости зданий и сооружений [1,3,5,6]. Основная идея ссйсмоизоляции состоит в том, чтобы увеличить основной период свободных колебаний здания и выйти из области преобладающих периодов сейсмических воздействий. Все виды системы ссйсмоизоляции соответствуют общему принципу, по которому структура разбивается на две части и между ними устанавливается сейсмоизоляция. Часть фундамента, которая опирается на грунт, называется субструктурой, а другую часть - суперструктурой [1]. Следовательно, защищаемый объект состоит из трёх составных частей: субструктура; сейсмоизоляция и суперструктура.

Assessment of seismic fault risks on spatial planning and development in aras sezs based on lulcIdentifying seismic fault zones is crucial for assessing the seismic risks and therefore affecting the land cover plan for a specific area. Urban areas built on seismically active fault zones are more susceptible to earthquakes compared to areas covered with dense forests or agricultural lands. The North- West Iran, Aras Special Development Zones (SEZs) are one of the areas with prominent land cover in near future due to its reachability to multiple countries. Analyzing the relationship between land cover types and seismic fault zones in the Aras SEZ can provide valuable insights into the susceptibility of different land cover types to seismic events. We used Land Use/Land Cover (LULC) method to assess the impact of seismic fault zones on land use in the Aras SEZs which involves evaluating the potential impact of earthquakes on different land uses and activities. This assessment can help identify areas that are most susceptible to seismic hazards and prioritize them for risk mitigation measures. In conclusion, our assessment of seismic fault risks on spatial planning and development in Aras SEZs suggests valuable insights to ensure the safety and resilience of future investments and developments.

It is shown that the earthquake resistance of buildings during construction in difficult ground conditions has a number of features. Traditional seismic isolation systems are used without regard to the properties of weak soils and do not consider these features. New, effective design solutions are proposed that meet the requirements of improving earthquake resistance and construction in difficult ground conditions. -

В данной работе мы рассматриваем понятие на сколько долговечны строительные конструкций, выявляем основные положения теории и оцениваем способы повышения долговечности и живучесть в сооружениях. Долговечностью или живучестью называют такое свойство строительных конструкций зданий и сооружений, которые продолжают выполнять свои функции при повреждении или обрушении какой-либо его части. Методика проверки конструктивных элементов базируется на первичных отказах, которые не должны приводить к разрушению остальных элементов.
