Design of Effective Statically Indeterminate Reinforced Concrete Beams

Stress analysis of four-story building to detect the crack location under the earthquake loading

“…the design resistance method of a reinforced concrete analysis considered the nonlinearity, which is the cracks happen after elastic phase passed during the failure. Kochkarev et.al. in 2020, develop the basic analysis to design the uniform beam structure in order to perform an effective structure analysis for beam reinforcement and reconstruction [6], in further, this research provide the stress and cracking analysis which applicable as the reference to perform the concrete structure retrofitting. Beam-column join is the critical zone in reinforced concrete building [7], such as the analysis result of the model in this research, there are stress concentration in beam and column intersection which indicate the beam column join of the building need to observed in further for the future works.…”

Stress-strain state of damaged reinforced concrete bended elements at operational load level

“…In the article (Lobodanov et al, 2021), the work of damaged reinforced concrete structures is investigated and calculation of such structures is given. The reduction of compressed elements cross-sectional area is more dangerous and important (Khmil et al, 2021b;Klymenko et al, 2019;Kochkarev et al, 2020). In such cases the damage does not only lead to load-bearing capacity decrease, but can also cause changes in the structure stress-strain state (for example, the transition from compressed to compressed-bended state of element due to damage).…”
