The results from the FE calculations in study I are compared with hand calculation formulas based on the classic theory of strength of materials, linear elastic fracture mechanics and the generalised Volkersen theory. The main aim of the present paper is to present a new approach in modelling ...
and moisture content which induce a maximum 18% variability over the ranges expected in design. System properties are also shown to be important, with stochastic phenomena such as delamination and encapsulation failure resulting in changes to the charring rate that cannot be easily predicted. Finally...
The focus lies on the explanation of the post-processing of experimental data into input data for design calculations. In this context, the aim is for practical engineers and researchers to have a better mutual understanding. Stiffness, ductility and force reduction factors will be especially ...
The calculations were carried out in the Design Builder program which allows preparing the simulation of the building envelope a... K Nowakdzieszko,M Rojewskawarchał 被引量: 1发表: 2014年 Possibilities of Using Prefabricated Modular Panels for Building NZEB Buildings in Earthquake-Affected Areas...
The results of the experiments were then used for comparison with calculation procedures according to the standard for the design of timber structures and with calculations according to the theory of linear elastic fracture mechanics. The experiments and the analytical models were supported by a simple...
Numerical calculations were carried out using a FEM model of the footbridge superstructure created in the SCIA Engineer software environment [24]. The processed spatial computational model (Figure 6) combines shell elements modelling main timber girders, steel cross-girders, and vertical stiffeners with...
Most of the tradeoffs, moreover, are predicated on short-term calculations from the standpoint of the economic status quo. But the status quo itself is unstable. The global human economy has already altered the environment in ways that may, eventually, prove irreversible and fatal to the biosphe...
Theoretical calculations were... A Pozdeeva 被引量: 0发表: 2015年 Ultimate strength of hardboard-webbed timber I-beam in shear Design formulae are given for timber I-beams with hardboard web subjected to short-term loading. The proposed formulae take into account of the postbuckling behaviour ...
This suggests that end support restraints should differ for static deflection and natural frequency calculations. Top loads have a predominant impact on end support restraints, and a larger top load results in a significant increase in the support restraint. However, this relationship is non-linear....
In the early stages of the design process only two physical models were used; later efforts included extensive drawings and apparently also mathematical modeling with numerical calculations. Wren had begun his career as a mathematician and physical scientist and was professor of astronomy at Oxford ...
