Research on reliability of steel roof structures subjected to snow loads at representative sites in China

Cold Regions Science and Technology, 2018
Abstract An appropriate probabilistic description of snow loads is important in reliability analysis. Probability distributions for annual maximum ground snow loads are studied in detail in this paper based on the samples of snow loads on the ground, which are simulated by a snowmelt model.

Reliability of Steel Truss Roof Systems Under Variable Snow Load Profiles

International Journal of Steel Structures, 2020
The probabilistic safety analysis of steel truss roof systems under variable snow load profiles is investigated. The roofs of structures such as industrial buildings or sports halls, which require wide areas, are frequently subjected to unexpectedly high loads.

Effect of Statistical Uncertainties in Ground Snow Load on Structural Reliability

IABSE Reports, 2015
<p>This paper studies the effect of commonly neglected statistical uncertainties on structural reliability. The failure probability of a generic structural member, subjected to snow load is analysed using frequentist and Bayesian techniques to quantify parameter estimation and model selection uncertainties in ground snow load. Various variable to

Reliability-based assessment of roofs in Japan subjected to extreme snows: incorporation of site-specific data

Engineering Structures, 2005
Abstract Performance-based engineering is a new paradigm in structural design for natural hazards. In this paper, the authors explore the problem of estimating regional variations in fractiles of snow load used for design purposes from a limited number of discrete observing stations. The reliability implications of such estimates are examined for the

Failures of Roofs under Snow Load: Causes and Reliability Analysis

Forensic Engineering 2009, 2009
Collapses of a number of roofs in Europe during the winter 2005/2006 initiated discussions concerning reliability of the roofs exposed to snow loads. Presented overview of extensive investigations of structural failures is focused on causes and consequences of failures.

Is the extreme snow depth record for nordland, norway reliable?

Geografiska Annaler: Series A, Physical Geography, 2016
A snow depth of 370 cm at Dunderlandsdalen in winter 1919–20 is the largest recorded at stations in Nordland, Norway. During the period 1895–1924, the average maximum annual value there was 150.4 cm; at other stations it ranged from 38.5 to 190.1 cm. The ratio of maxima at other stations to that at Dunderlandsdalen was particularly low in 1919–20.

Reliability-based snow load maps for building design

2015
This paper describes the development of a new snow load map for defining ground snow loads for building (roof) design in the state of Colorado. The newly proposed Colorado maps aim to ensure that structures designed across the state achieve the target safety index of 3 defined in ASCE 7.

Reliability of Steel Hall in Zenica Loaded by Snow Load

2019
Snow load is the dominant load for steel structures of hall in Zenica, Bosnia and Herzegovina. Existing structures are calculated in accordance with the JUS regulations that were valid in the former Yugoslavia. The snow load was based on the values proposed in the DIN regulations of 1936 and used until the development of new regulations according to ...

Reliable jump detection for snow sports with low-cost MEMS inertial sensors

Sports Technology, 2011
Body-mounted devices, incorporating low-cost micro-electromechanical systems (MEMS) Inertial Measurement Units (IMUs), for real-time sports performance feedback are commercially available. In sports such as skiing, snowboarding, and mountain biking, aerial jumps can be detected with these devices and performance variables including air time and jump ...
