“…It should also be noted that the issues on calculating an increase in the strength of concrete under the multi-axes stressed state were left unresolved or not adequately solved. Studies by different scientists contain significant differences in the numerical values for the results obtained [9][10][11][12][13][14][15]. The reason for this is that the percentage of an increase in the bearing capacity of a steel-concrete structure, as a result of the transformation of the uniaxial stressed state into the multi-axes one, depends on many factors.…”

Розрахунок сталебетонних балок проводиться з жорстким з'єднанням бетону зi сталевою смугою. Це можливо здiйснити, якщо встановити жорсткi упори, якi перешкоджають змiщенню смуги вiдносно бетону. Зусилля, дiюче на упор, кiлькiсть жорстких упорiв та крок визначаються через кути повороту мiж двома сумiжними упорами. Для визначення зусиль, дiючих на жорсткi упори, та кроку необхiдно спочатку визначити кут повороту мiж двома сумiжними перерiзами в межах балки. Кути повороту перерiзiв визначаються графо-аналiтичним методом. Розрахунок по деформацiям залiзобетонних та сталебетонних балок виконується за приведеними жорсткостями поперечних перерiзiв. При вибору кроку жорстких упорiв та їх кiлькостi необхiдно прагнути оптимiзувати конструкцiю сталебетонних балок. Оптимiзацiя полягає в тому, щоб максимальнi напруження в сталевiй смузi дорiвнювали її граничному значенню, а зусилля, дiюче в упорах, та крок упорiв були однаковими. Для того, щоб зусилля в кожному упорi були однаковими, необхiдно нульову дiлянку робити меншу за iншi. В ходi дослiджень був розроблений алгоритм пiдбору кiлькостi, кроку жорстких упорiв та зусиль в них. Пiдбiр проведено по завданим характеристикам використаних матерiалiв, дiючого зовнiшнього навантаження, довжинi балки, звiсним розмiрам поперечних перерiзiв бетону та сталевої смуги. При цьому зусилля в усiх упорах однаковi, крок упорiв, окрiм нульової дiлянки, постiйний, максимальне зусилля в сталевiй смузi, виникаюче в серединi прольоту, не перевищує граничного значення, отриманого за розрахунком. Наведений алгоритм дозволяє проводити розрахунок жорстких упорiв при завданому значеннi зусиль, що дiють на них при iснуючому навантаженнiКлючовi слова: сталебетонна балка, жорсткий упор,крок упорiв, зусилля в упорi, сталева смуга, приведена жорсткiсть, графо-аналiтичний метод UDC 624.072.31

“…Рост популярности сборно-монолитного домостроения объясняется конструктивной гибкостью данной строительной системы, выражающейся в достаточно удачных возможностях сочетания положительных моментов отдельно сборного и монолитного вида строительства с минимизацией их минусов. Отечественные и зарубежные учѐные проводят различные исследования по изучению конструктивных особенностей сборно-монолитных зданий и сооружений, причѐм как отдельных их конструктивных узлов и элементов [1,2,5,8,9,[10][11][12]19], так и зданий (фрагментов зданий) в целом [6,7,13,[14][15][16][17][18][19].…”

The performance and structural reliability of concrete-to-concrete joints play an important role in precast-cast-in-place constructions, since they are responsible for deformation of concretes of different age, type and strength. The paper studies the effect of the joint type on its bearing capacity under shear loads. A horizontal test bench and a standard vertical press are used in the experiment to provide the shear load along the concrete-to-concrete joint (light cast-situ and heavy precast concretes). The following joint installing is considered: a smooth surface, which provides the concrete joint due to the adhesive and friction forces, and the joint provided by transverse reinforcement. Design features are identified for the joint bearing capacity exhaustion in concretes of different age, type and strength in precast-cast-in-place constructions under shear, depending on the joint type. A comparative analysis is given to the results obtained. It is shown that the transverse reinforcement has a positive effect on the bearing capacity of the concrete-to-concrete joints.
