The formation of Ulyanovsk (Simbirsk) planning structure is viewed by component-wise changes analysis of city planning structure with the revealing of these changes correlation in course of study of planning structure genesis. The stages of city quantitative growth and its planning organization qualitative changes are examined. Quantitative growth of city road network and its quality changes over time are considered. The stages of urban centers formation - nodal and linear - are viewed. Processes of intensive and extensive development of the centers are described. Quantitative growth rates for all components of the planning structure of Ulyanovsk (Simbirsk) are presented. These indexes are summarized in the table. The genesis flowchart of Simbirsk-Ulyanovsk planning structure is done.

The article views the questions of using of constructions based on nature principles in modern architectural objects. A brief analysis of history of bionic structures development on the example of Gothic is given. Modern objects of famous architects having nonlinear structure and complex structural system are examined. The article presents the objects designed and built mainly in China during the last 3 years. A detailed description of the materials and compositional techniques is presented. The latest technologies used in the construction in advanced industrial countries permit to create surfaces of any curvature like the natural surfuces. Тhe close collaboration оf an engineer with an architect for the creation of structures, structural systems and architectural objects shell is described.

The article views the new (innovative) methods and the problems of teaching in design in the Russian educative system. The general description of teaching methods is given and the methodological problems in contemporary design-education are defined, conceptual and terminological meaning of innovation in educational process is specified. The comparative analysis of two methods developed and tested in some russian universities of architecture is done, their base principles and the common points are noted and the differences between them as well as their attitude towards traditional education system of design in Russia are viewed. The conclusions about the possibility of these methods application in practice are proposed.

In the article life and creative work of famous Samara architect Vasily Sukhov - the author of the Samarsky Dom Promyshlennosty (the Samara House of Industry) built in 1930-ies - are viewed. The never-before-seen information is published for the fi rst time, it is the missing piece of the image of Samara constructivism of 1920-1930-ies [1-13].

The article is devoted to the issues of industrial wastewater treatment using reagents received from productions wastes. The structure and properties of waste formed by production of titanium products containing ions of the titan, aluminum and iron are investigated. Modeling the process of receiving the reagent based on titanium sludge is made, its coagulating properties are investigated. During receiving process, modeling special att ention is paid to removal of the fl uorides, which are present at sludge. Effi ciency of the received titanic coagulant in comparison with known «Аква-АуратТМ30» reagent is shown. It is experimentally confi rmed that for production of a coagulant it is necessary to use the sludge, which is selected, in a place of its direct education. It is made a conclusion about the possibility of titanium sludge use for receiving reagent and its further use for purifi cation of industrial sewage.

The main results of inspections of technical condition of hydraulic engineering constructions of the lake Kazenny on the draw Atyukhta in Grushevka river basin are presented in the article. According to natural observation the dam and the transmission facilities have a lowered level of safety, the constructions are under precritical conditions. In this regard arrangements for reliable and safety operation of hydraulic engineering constructions of this pond are proposed, and the need for reconstruction is proved.

The problems of ecology, of industial waste utilization lead to search of optimal concrete mixtures. The question of modern coatings for roads and sidewalks is viewed. The interactions of paving products and industrial wastes of metallurgical production are studied. The advantages of cement in comparison with asphalt-concrete materials are shown - their environmental compatibility, sustainability, quality. Experimental results are given on the basis of empirical data and their meanings.

A new resource effi cient solution for damaged stone walls support structure of a building is proposed in the article. This design solution is developed in construction fi eld and can be applied for the repair, strengthening and reconstruction of buildings and structures, and more particularly it is can be used to correct sever damages and to ensure the spatial rigidity of stone walls of a building. Stone walls of building are strengthened by beam tensible band containing longitudinal and transverse bars in the form of steel joists and a device for their articulation and tension, which consists of an anchor cleat and att achement screws with tension nuts. The support device is elaborated taking into account spatial rigidity and load-carrying capacity of existing structures without their dismantling. Positive technical results are obtained due to increased operational reliability and walls spatial rigidity.

The results of experimental studies of thermal state of heat transport lines are viewed. Ready-to-use PU foarm unsulation in polyethylene sheath is taken as thermal insulation of heating system lines under the ground. Readyto- use PU foarm unsulation in sheet galvanized steel sheath is taken as thermal insulation of heating system lines aboveground. Experimental results permit to determine real heat losses of heat transport systems.
