Construction Accidents

Accidents from falls are a serious problem in the construction industry in Japan, where approximately 40% of fatal construction accidents are caused by falls. FRP inspection platforms are used for fall protection during bridge maintenance and management works. These structural elements are usually set on the side of an abutment for the inspection of the joint located between the abutment and a bridge girder. The hook of a safety belt is then fastened onto the guardrail of a platform when work is executed at a high location. Nevertheless, the degree of platform safety remains uncertain because of the properties of the FRP platform. In this study, therefore, the safety of a platform was experimentally confirmed through the use of 75-and 85-kg sandbags and a 100-kg human dummy. Results show that platform safety improved, as indicated by the sandbags remaining firmly attached to the hook latched onto a platform railing when they were dropped during the experiment.

The article presents the results of archaeological studies carried out at the Yakushkino 3 settlement attributed to the Kashino culture of the Early Iron Age (subtaiga Tobol area, Western Siberia). The settlement was preliminary dated at the 4th–3rd centuries BC. In this work, the authors set out to study the house-building tradition of the Ka-shino culture using the Yakushkino 3 settlement as an example, create its graphic visualisation; identify certain characteristics of the structure defining the nature of the settlement — seasonal use or place of permanent resi-dence, which indicate the adaptation strategies of the population. In 2016–2017, two structures connected by a passage were studied at the settlement. The former is interpreted as a residential structure, whereas the latter is thought to have been used for utility purposes. The multi-chamber residential structure (ca 48 m2) was chosen for the reconstruction. To this end, the authors employed the method of theoretical reconstructions. Drawing on the planigraphy and stratigraphy of the excavation site, the main elements (foundation pit boundaries, pits, ditches, etc.) of the structure were identified. The authors defined the layout of the structure on the basis of the character-istic arrangement of structural elements; identified techniques used in the construction of walls and roofs; deter-mined the possible use of certain building materials; as well as suggested interior variants. Finally, a graphic image of the structure was created. As a result of the study, the following assumptions were made. The structure con-sisted of 4 near-square rooms: the main central chamber (1) — 25 m2; chamber 2 — 12.5 m2; chamber 3 — 6.75 m2; chamber 4 — 3.5 m2. The second chamber was divided into two unequal parts, with ceramics being concentrated in its larger part, which could serve as a kitchen or a dining area. Chambers 3 and 4 could be used as bedrooms or as utility rooms. There was no hearth in the structure. The structure had a frame, with vertical posts providing support for the roof beams and being part of the frame-wall construction. The walls could be constructed of wicker boards or erected by leaning poles against the upper beam of the frame. The roof could be gable, covered with reeds and poles. Against the background of uniform buildings of the Early Iron Age, Kashino dwellings are cha-racterised by one common structural detail that was traced in the layout of the dwelling from the Yakushkino 3 settlement — additional chambers (utility or sleeping rooms) attached to the main room without an additional cor-ridor. This fact distinguishes these buildings from the dwellings of the Sargatka or Gorokhovo cultures of the Early Iron Age (Western Siberia). The absence of a hearth and the lightness of the construction suggests that the dwel-ling from the Yakushkino 3 settlement was used in the spring-autumn period.

Rapid Deformation

For a floor of a building with no less than four stories and no more than twelve stories, the two-hour fire resistance performance should be satisfied. In the case of slabs with steel studs, no two-hour fire resistance performance has been proposed in Korea. In this study, the two-hour fire resistance performance of slabs with steel studs performing as structural elements of modular buildings was evaluated. These specimens were redesigned based on the typical slab used in Europe and North America by modifying the 45 mm fire-resistant board to achieve two-hour fire resistance. The experimental results showed that the FR-001 specimens with 140 mm mineral wool applied to the lower slab and the FR-002 specimens containing 100 mm lower-slab glass wool and 150 mm upper-slab mineral wool did not satisfy the two-hour fire resistance performance, owing to the rapid deformation of the specimens after 75 and 110 min, respectively. However, the FR-003 specimens containing 100 mm glass wool, 150 mm mineral wool in the upper slab, and concrete in the slab satisfied the two-hour fire resistance performance requirement.

Questions of an estimation of reliability of building construction depending on methods of calculation taking into account properties of building materials and operating conditions are under consideration. The required level of reliability is ensured not only estimated the requirements of design standards, and also depends on the methods of calculation adopted design scheme, the appearance of connections of structural elements and rules of design, plan check tests and the acceptance criteria in the manufacture and installation.
