The article is aimed at showing that for the organizational and technological solutions optimal choice when designing a construction object, it is necessary to take into account energy saving factors. The criteria importance assessment for energy-saving measures at the construction organization project design stage is given. The procedure for using the pairwise comparisons matrix allows to perform an optimal search for energy-saving measures, which will lead to the effective organizational and technological solutions choice at the design stage.

56Из массива накопленных значений для разных значений выбираем тот индекс, для которого является максимальным.На рис. 2. выходы подпрограммы «Radiation pattern.vi» подключены к соответствующим терминалам вывода найденных значений и . Весь код сосредоточен в цикле «While Loop», где условием остановки цикла является нажатие кнопки «stop».Вывод. Исследования, проведенные на модели показали, что определе-ние пеленга методом формирования диаграммы направленности [1] обладает более высокой помехозащищенностью, чем, например, находящийся в экс-плуатации радиопеленгатор АРП-75 (обеспечивает работоспособность при уровне шума ниже 30 % от уровня основного сигнала, а рассматриваемый ме-тод -при уровне ниже 90%).Разработанная модель использовалась при выполнении опытно-конструкторских работ «Перспектива» в ОАО НПК «Русская радиоэлектро-ника».
The article deals with the change in the deflection of partially prestressed elements under repeated loading. Depending on the classes and the ratio of stressed and non-tensioned reinforcement, the effect of different levels of the repeated load application on the deformability index of the bent ferro-concrete elements is analyzed. Analysis of the experimental and calculated values of deflections of rectangular profile beams after application of static repeated loads showed that regulatory documents underestimate the effect of the operational level repeated loads on the change in deflections at both average and high loading levels by more than 30%. Comparison of deflection values was made immediately after application of repeated loads at the level of 60% from the destructive ones and after lifting the load to the level of 80%. To correct the values of deflections within the limits of the calculated dependences of the norms, when subjected to the operational level repeated loads, it is proposed to take the value of the coefficient characterizing the elastoplastic properties of concrete equal to 0.3 for practical calculations. The results of the study increase the convergence of the experimental and theoretical values of deflections in the range considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
