Thin Walled

At present, there is a renewed interest in the design and application of wall structures in architecture and construction. With the advent of modern computers, refined methods for calculating shells, new building materials, the development of differential geometry and the rapid growth of numerical methods of calculation, it became possible to create architectural masterpieces from shells of canonical and non-canonical forms, which can be the hallmark of a city or country. This emerging trend among young Russian and foreign specialists inspires optimism among scientists who are researching thin-walled shells. The article considers some results of the work of the Department of Civil Engineering of the Engineering Academy of the Peoples Friendship University of Russia on attracting students to architectural design and involving undergraduates in researches on architecture, the theory of thin-walled spatial structures and their application in construction and architecture. The publications of students in this field are presented.

Wall Structures

Traditional Iranian houses, were built of heavy, voluminous building materials resulting in massive bearing wall structures. Such buildings had fixed architectural spaces, with defined boundaries and dimensions. However, the need for adaptability was fulfilled through creating multifunctional spaces, seasonal or even daily movements in the horizontal and vertical directions of house areas, and subdivision or expansion of the primary spaces. Urbanization in Iran is leading to gradual replacement of individual houses by residential complexes and apartments in which, the use of traditional design principles was lost, while solutions to enhance adaptability in the internal layouts have not yet developed. The paper concludes that open building may provide practical tools to enhance spatial variations in the new conditions. However, to take the first step towards this approach in Iran, some major issues such as "legal framework", "changing needs of Iranian families", "Iranian life styles" and "situation of industrial building production in Iran" have to be analyzed. Considering the mentioned factors, some recommendations for architectural design are proposed.

Thin Walled

After a period of relative calm in the construction and design of thin-walled large-span shells and network multilayer shell structures, which, according to the world's leading architects, began in the 1980 s, the time has come for the expanded use of spatial structures in the architecture of public and industrial buildings. Less commonly, shells are used in small-sized housing construction: ecological villages, noospheric and bionic architecture. The entire 20th century did not stop research on the development of analytical and numerical methods for analyzing shells for strength and stability, for the creation of new building materials. Geometers have created and studied more than 600 analytical surfaces that can be mistaken for the mid-surfaces of civil and mechanical engineering shells. As a result, by the beginning of the 21st century, architects and engineers had all the necessary tools to continue the traditions of the "golden age of shells". The analysis of problems with the use of new forms in parametric architecture, carried out in the article, showed that more than ten classes of surfaces from their classification have not yet found application in architecture and mechanical engineering. It is assumed that the number of applied classes of surfaces will not expand, and new ideas for the shaping of shells will be based on the use of already well-known surfaces, namely, surfaces of revolution, transfer, umbrella, minimal, ruled and wavy surfaces. Mainly, shell structures will be designed taking into account environmental, energy-saving requirements and transforming structures.

History Of

There has been a long history of applying metal to architecture. At the beginning, they just appeared in the structure of bridges, factories and storages, and then gradually turned up as a form of building structural materials in civil architecture such as markets, schools and office buildings. So all the time, metal like steel structure or hardware impresses people as a kind of industrialized building materials. With the development of architectural technology and the researching of characteristics of building materials, metal material has been brought in building skin design with brand-new appearance, and coruscate new vitality in the field of architectural design depending on full of variety of expressions and economic environmental character.

In contrast to methods that do not take into account multiconnectivity in a broad sense of this term, we develop mathematical models and highly effective combination (BIEM and FDM) numerical methods of calculation of stationary and quasi‐stationary temperature field of a profile part of a blade with convective cooling (from the point of view of realization on PC). The theoretical substantiation of these methods is proved by appropriate theorems. For it, converging quadrature processes have been developed and the estimations of errors in the terms of A. Ziqmound continuity modules have been received.

The paper presents new results in the building materials area. One of the solutions of the thin-walled elements obtaining can be achieved due to new additive using. The main purpose of the paper was improvement concrete properties for thin-walled constructive elements. The experimental and standard methods have been used and new complex additive for concrete. The research shows that a comprehensive additive consisting of aqueous solution of polycarboxilate polymer, silica sol and potassium nitrite is effective and makes it possible to produce high-efficiency concrete with unique properties: higher compression strength, higher crack resistance, frost resistance, water resistance, abrasion resistance. The study shows that the concrete is chemical resistant. Modified concrete can be recommended for manufacturing critical concrete structures of special purpose, for example high-rise constriction.
