Journal of the Structural Division, 1967
The paper describes a simplified formulation of factors that can be used in design to evaluate certain dynamic effects of the wind, principally the effects of gusts. The material was prepared for use in conjunction with a new Scandinavian wind load code.

Aircraft Engineering and Aerospace Technology, 1941
THE values of the load factors used in de‐signing an aeroplane are almost direct measures of its strength. They also affect the weight of a certain portion of the aeroplane structure. Although the percentage of gross weight that depends directly on the magnitude of the design load factors is not as large as might be supposed, it represents a ...

Probability Based Load Criteria: Load Factors and Load Combinations
Journal of the Structural Division, 1982This is the second of two papers that describe a study conducted to develop probability-based load factors and load combinations suitable for use with common construction materials and technologies. In the second phase of the study, described in this paper, the checking equation format for the proposed load criteria was selected, and the load factors ...

Aircraft Engineering and Aerospace Technology, 1931
IN this issue appears a summary of a paper prepared by two of the research workers of the National Advisory Committee for Aeronautics which is most opportune. A number of minds, both among designers and scientists, have been exercising themselves with thoughts as to what may be the effect on a modern aeroplane of meeting a vertical current, commonly ...

THE major problems connected with the development of satisfactory structural strength requirements have long since been solved. We have, in this country, an empirical system of specification which fulfils the fundamental criterion of any strength system, namely, that failures in the air through lack of adequate strength of any component of an aircraft ...

Personality and Individual Differences, 1987
Abstract Each of 17 tests was embedded in six different eight-test matrices. Stability of general factor loadings were determined over the six contexts. Correlations of factor loadings ranged from 0.52 to 0.94 with an average value of 0.83.

In this chapter, attention is focused on the cognitive load factor. In Sect. 6.1, I describe some aspects that constitute the technical notion of mental workload. Afterwards, I briefly illustrate the metaphor of the filter and the resources metaphor, both of which are supposed to explain the limits of human beings in executing multiple tasks (Sect. 6.2)

Simplified load combination factor for snow load
Structural Safety, 1993Abstract The load combination factor for snow load is formulated by a simplified development based on Turkstra's rule for load combination and the Gumbel distribution for the snow load model. The probability of exceedance expression is compared with an existing probabilistic load model.
