The computational efficiency of random field representations with the Karhunen-Loève expansion relies on the numerical solution of a Fredholm integral eigenvalue problem. In this contribution, different methods for this task are compared. These include the finite element method (FEM), the finite cell method (FCM) and the Nyström method. For the FEM with linear basis functions, two different app...

Confusion in the literature about the definition and calculation of repetitive member factors is identified. This confusion casts some doubt on the validity of the 1.15 repetitive member factor permitted in ASTM standards D245 and D1990.

Analytical approximations to Einstein integrals are proposed. The approximations represented by two fast-converging series are valid for all values of their arguments. Accordingly, the algorithm can be easily incorporated into professional software like HEC-RAS or HEC-6 with minimum computational effort.

This work concerns an assessment of the behavior of infilled frames. The feasibility of possible immediate implementation of some recent developments both in analysis and design of infilled frames for practical design is investigated. It is now widely recognized that masonry infill panels used in reinforced concrete (R/C) frame structures, significantly enhance both the stiffness and the streng...

After a brief introduction on vehicle barriers in general, the writers present a rational basis of determining a design force on security barriers. The design force is derived from rigid barrier impact deceleration values culled from published literature on vehicles with similar kinetic energy. The Appendix provide a summary of references for further study. DOI: 10.1061/ ASCE 1084-068

Laboratory and field tests have shown that accelerated compression of peat soils occurs in response to moderate heating and an effective overconsolidation is produced on subsequent cooling. This phenomenon has been termed thermal precompression. In this study, long-term laboratory and field tests were conducted to investigate secondary compression behavior of peat as a function of stress and te...
