“…Uzyskane wyniki analiz pozwoliły na opracowanie formularza wstępnej oceny bezpieczeństwa rusztowania budowlanego wykorzystującego zaproponowane cząstkowe współczynniki zagrożenia (W j ), umożliwiającego wstępną ocenę prawdopodobieństwa zaistnienia zdarzenia wypadkowego na rusztowaniach budowlanych w odniesieniu do populacji badanych wypadków przy pracy (W z ) oraz populacji rusztowań budowlanych. Populacja rusztowań budowlanych została oszacowana na podstawie otrzymanych wyników badań projektu "Model oceny ryzyka wystąpienia katastrof budowlanych, wypadków i zdarzeń niebezpiecznych na stanowiskach pracy z wykorzystaniem rusztowań budowlanych" ("ORKWIZ"), zadania dotyczącego analizy ilościowo-jakościowej rusztowań budowlanych stosowanych w Polsce (Bucoń, Czarnigowska, Kmiecik i Robak, 2019). Formularz opracowano w formie elektronicznej za pomocą programu MS Excel.…”

“…In the years 2016 to 2018, the project entitled: "Modelling of risk assessment of construction disasters, accidents, and dangerous incidents at workplaces using scaffoldings" (ORKWIZ) was conducted. The main aims of the research were to perform scaffolding tests in the aspects of ensuring employee safety [11][12][13][14][15][16][17][18][19][20][21], studies on the safety culture of employees [22,23], an analysis of the causes of over 180 accidents on scaffolding [24,25], and research on the amount of scaffolding used in Poland depending on the season [26]. Additionally, examples of the errors of scaffolding assembly that negatively affect their carrying capacity were shown in paper [16].…”

Influence of Foundation Quality on the Stress in the Elements of Steel Façade Scaffolding

2020

The purpose of this paper is to show the influence of incorrect scaffolding foundations on the stress in their elements. Static stress analysis was performed for exemplary steel façade scaffolding. The scaffolding was formed using the Plettac 70 system and was composed of 16 modules and 13 working levels. The total dimensions of the scaffolding were 45.0 × 26.36 × 0.74 m. The scaffolding was set up partly on concrete and partly on a created ground classified as coarse sand with discontinuous graining. The boundary conditions modelling the foundation considered the heterogeneity of the ground both along the scaffolding and in the direction perpendicular to the façade. The effect of uneven subsidence on the scaffolding frames was checked, adopting a constant stiffness of 3500 kN/m in half of the supports, while in the rest of them the stiffness varied from 35 to 3500 kN/m. Due to additional bending moments, normal stresses in stands and transoms of the frames increased. Incorrect scaffolding foundation has the greatest negative effect on normal forces in anchors and bracings. Because these elements are responsible for the stability of the scaffolding, their damage may result in scaffolding failure and would certainly lead to a reduction of the values of free vibration frequencies, thus resulting in the discomfort of the workers on the scaffolding and a lack of safety.

The paper presents static-strength analyses of 120 scaffoldings used on construction sites in Poland in the period 2016-2018. The geometry of each analysed scaffolding was taken from measurements made on the construction sites, and the scaffolding loads were determined on the basis of the standards requirements. The results of scaffolding inventory, surveying measurements, measurements of axial forces in standards, and measurements of scaffolding accelerations during vibrations were used to create numerical scaffolding models. For each scaffolding, buckling load analysis and linear static analysis were performed for four load cases which took into account self-weight, parallel and perpendicular wind actions and service load. On the basis of numerical analyses, it was found that 14 scaffoldings could fail due to loss of stability. For 56 scaffoldings, the ultimate limit state condition was not met in at least one group of components, therefore 47% of tested scaffoldings should not be approved.
