Analysis of scaffolding harmonic excitation

Jarosław Bęc, Ewa Błazik-Borowa, Jacek Szer

Bulletin of the Polish Academy of Sciences. Technical Sciences > 2023 > Vol. 71, nr 1 > art. no. e144577

Scaffolding is equipment usually used at construction sites. A scaffolding structure is lightweight and made of elements used many times. The characteristics of scaffolding make it susceptible to dynamic actions present at the structure or occurring nearby. A scaffolding structure of medium size was subjected to analysis in this paper. The structure FEM model was loaded with single force harmonic...

Metoda oceny ryzyka wystąpienia sytuacji potencjalnie wypadkowej na rusztowaniu

Ewa Błazik-Borowa, Krzysztof Czarnocki, Agata Czarnigowska, Iwona Szer, more

Przegląd Budowlany > 2022 > R. 93, nr 7-8 > 42--50

W pracy przedstawiono metodę oceny ryzyka wystąpienia sytuacji potencjalnie wypadkowej na rusztowaniu. Metoda składa się z zestawu badań, które są niezbędne do oceny pracy na rusztowaniu w aspekcie bezpieczeństwa, i modelu ORWKIZ, który określa sposób wyznaczenia grupy zagrożenia, jakie występuje na rusztowaniu. Model uwzględnia czynniki prawno-społeczno-ekonomiczne, czynniki środowiskowe, czynniki...

Influence of dynamic properties on scaffoldings safety

Ewa Błazik-Borowa, Jarosław Bęc

Archives of Civil and Mechanical Engineering > 2021 > Vol. 21, no. 4 > 145--158

Scaffoldings are used for works at height and in places that are hard to reach, which makes such works dangerous to employees and accidents occur frequently. Loads generated by scaffolding users cannot be avoided. Moving workers excite low-frequency (1–2 Hz) vibrations and scaffoldings as slender structures are prone to such dynamic action. The method for determining the probability of vibrations...

Probability distribution functions for service loads of frame scaffoldings

Ewa Błazik-Borowa, Michał Pieńko, Iwona Szer, Bożena Hoła, more

Bulletin of the Polish Academy of Sciences. Technical Sciences > 2021 > Vol. 69, nr 2 > art. no. e136734

The paper discusses service load measurements (weight of construction materials, small equipment and workers) conducted on 120 frame scaffoldings all over Poland in 2016‒2018. Despite the fact that the scaffolding should ensure the safety of its users, most accidents on construction sites are caused by fall from height. Service loads are one of the elements affecting the safety of scaffolding use...

Influence of the seasons on construction site accidents

Iwona Szer, Jacek Szer, Monika Kaszubska, Jakub Miszczak, more

Archives of Civil Engineering > 2021 > Vol. 67, nr 3 > 489--504

The article analyses the changes occurring in accidents in the construction industry in Poland. It was analyzed the influence of the season on the number and structure of accidents. Research and analyzes were carried out on the basis of statistical data, made available by the Central Statistical Office, regarding accidents at work in construction that occurred in the period from 2010 to 2018. The...

The impact of equipments of animal passages on their efficiency

Ewa Błazik-Borowa, Michał Jukowski, Janusz Bohatkiewicz, Janusz Rymsza

Roads and Bridges - Drogi i Mosty > 2021 > Vol. 20, no. 4 > 379--396

The paper describes the impact of the individual components of animal passages on the efficiency of their use. Research was conducted with regard to four species of ungulates: elk, deer, roe deer and boar. The analyzed equipment are road lighting, shielding vegetation, rootwood and tree stumps, anti-glare shields, rocks, fencing. The analysis were made on the basis of surveys which were filled by...

Façade scaffolding behaviour under wind action

Tomasz Lipecki, Paulina Jamińska-Gadomska, Jarosław Bęc, Ewa Błazik-Borowa

Archives of Civil and Mechanical Engineering > 2020 > Vol. 20, no. 1 > 375--389

The main objective of the study was to estimate the mean horizontal wind action on a façade scaffolding on the basis of full-scale data. Measurements of climatic parameters were carried out for a number of façade scaffoldings (120 structures) located in Poland over a 30-month period. The measurement points were located on 2–3 deck levels of each structure and at 2–4 points placed in each level. The...

Numerical Models of Scaffolding Decks and Their Applications

Ewa Błazik-Borowa, Aleksander Robak

International Journal of Civil Engineering > 2017 > 15 > 7 > 979-989

This study presents methods for numerical modelling and the static computer analysis of steel decks fixed on scaffoldings. The main problem raised here is the method of creating models of a single deck and determination of the accuracy of every model for various design situations: the analysis of state stress in components of decks, the strength analysis of scaffolding, where decks can be loaded by...

Numerical analysis of load-bearing capacity of modular scaffolding nodes

Michał Pieńko, Ewa Błazik-Borowa

Engineering Structures > 2013 > 48 > Complete > 1-9

The paper is concerned with the numerical analysis of a node in modular scaffolds used for construction work. The purpose of this study is to determine the capacity of a node on the basis of the numerical analysis taking into consideration two factors: nonlinear material and the interaction between particular joint elements. The main subject of the analysis are the connections between the brace and...
