The influence of the geometric characteristics on the behavior of braces with restrained buckling - case study of perforated steel core. IOP Conf. Ser. Mater. Sci. Eng. Pub Date : 2024-03-01 C P Mocanu Basalic, S G Luca, I Lungu, P Mihai
Buckling restrained braces are elements that equip the building with additional capacity for resistance and stability when subjected to earthquakes. As an answer to the problem of the possible loss of stability of the buckling-preventing component, the “perforated-core buckling restrained braces” (PCBRB) is a concept that involves the introduction of gaps, in the core of the bracing, to control the

Variable diameter pile foundations – advantages and disadvantages IOP Conf. Ser. Mater. Sci. Eng. Pub Date : 2024-03-01 O E Colţ, C P Neagu, A Motău, I Dmitriev, L Chercheja
Variable diameter pile foundations can be an efficient foundation solution used for special structures, mainly for the ones with increased heights. For economic efficiency in land use, especially in urban areas, there is a tendency to build very high constructions with very small footprint related to their height, which transmit large loads to the foundation soil. Based on these aspects, it is necessary

Predicting multi-span bridge maximum deflection: Numerical simulation and validation IOP Conf. Ser. Mater. Sci. Eng. Pub Date : 2024-03-01 M Brinissat, R P Ray, R Kuti
Deflection is one of the main parameters often required to reflect and monitor the overall health state of bridge structures. Several approaches have been developed to monitor deflection accurately and economically. This research proposes a theoretical method to estimate the maximum deflection of the longest section of a seven-span continuous bridge using stress data collected through strain gauges

Computational assessment regarding structural rehabilitation of a reinforced concrete decanter tank IOP Conf. Ser. Mater. Sci. Eng. Pub Date : 2024-03-01 D Covatariu, A Filip, G Covatariu
The article describes the analysis of an industrial structure (reinforced concrete decanter tank for the drinking water’s storage in the Iasi – Romania area) in order to justify the proposals for structural rehabilitation to ensure structural stability. In this regard, a computational model was created in Graitec Advanced Design, using the physico-mechanical characteristics of the materials (concrete

A design tool for the analysis of reinforced and prestressed concrete columns IOP Conf. Ser. Mater. Sci. Eng. Pub Date : 2024-03-01 B Kovacs, T-N Toader
This article aims to describe an automatic calculation algorithm developed for the analysis of reinforced concrete and / or prestressed concrete columns. The article describes two analysis types: sectional analysis and analysis on the element. The sectional analysis consists in the generation of three characteristic curves: bending moment - curvature (M-1/r), axial force - bending moment (N-M) and
