Building structural systems with light gauge steel framing technology are steadily gaining popularity due to their huge advantages over traditional technical solutions. As a result of the competitiveness inherent in LGSF technology, its application is gradually increasing in the manufacture of both bearing and nonbearing structures. At the same time, the actual absence of national standards for seismic design requires the development of programs and the implementation of research and development work to study the behavior of LGSF buildings in the conditions of seismic impact. The article touches upon the main problems of antiseismic construction of LGSF buildings and presents the results of domestic and foreign research.

Physical Principles

The approach to creating standard means for reproducing units of volumetric activity of radon and thoron and flux density of radon from the soil surface is described based on the physical principles of reproducing these units of quantities and using as technical means for reproducing bubblers with a radioactive solution of radium salt, reference capacities of known volume, emanation chambers for generation of a toron, a gamma spectrometer with a semiconductor detector from highly pure germanium and radon radiometers. Reproduction consists in the physical realization of units in accordance with their definition as applied to the formation of radon and thoron in the radioactive rows of radium and thorium. The proposed approach will allow to determine the structural, structural and other technical solutions of standard measuring instruments, as well as specific techniques and methods of working with them. The creation of standard tools and technologies for reproducing units of volumetric activity of radon and thoron and the density of radon flux from the soil surface will ensure the unity and reliability of measurements in the field of ionizing radiation, traceability of units and bringing the characteristics of national standards in line with world achievements.

And Control

As a result of years of research and development work on subsea completions, manifolds and flowlines, followed by field installations in relatively shallow and calm waters, a number of well completion and flowline laying and connecting methods are available and operational. The installation methods are basically diverless and control and maintenance are achieved by sophisticated systems; likewise the floating offshore terminals such as the E.L.S.B.M. and the Spar have been designed, built and put into operation. Although these systems were meant to be installed mainly in deeper waters, say beyond 210 m where diver access and the use of conventional techniques would become rather limited for technical and economic reasons, it is now evident that many fields in shallower waters can be more economically and efficiently developed or complemented by the use of deepwater techniques. Current development work concentrates on the design and evaluation of multibore production risers, floating production platforms and pipelaying and repair.
