The paper deals with the chosen buildings of unagricultural functions on Lower Silesian villages. They are often social security homes, old people’s homes and hospitals. These houses, distinguished by big cubature and architectural forms dominate the given vil­lage architecture. Three examples of such buildings, localized in the Lower Silesia provin­ce, are presented in the paper: in Małkowice village near Wrocław, in suburbs of Ząbkowice Śląskie and in the small village Brzostowo. In the space of years they often were not used in agreement with their assignment for example as schools or dwelling houses, and now they are returning to their primary functions.

Article has review character. Be consecrated regional architecture as well as bu­ilding materials, from which these buildings came into being. Except generally received types of the regional architecture authoress would like to turn the attention also on with pretence nothing to distinguish oneself country architecture which contributes thanks local building material to individualized buildings in region and the general spatial order. There­fore except typical examples of regional buildings, as the Tatra Highlands architecture, or sudecka the authoresses call from kłodzko region the also typical Polish villages, in which the local stone is one of basic building materials architectural and decorative.

In this article has been presented comparison of values and distribution of bend­ing moments for three monolithic perpendicular tanks with the same dimensions, but dif­fer from walls thickness and construction. Analysis results concern of standing on ground tanks, .lled with liquid. Also in.uence of temperature has been taken.

Aggregates are important components of concretes. However, resources of natu­ral deposites of them are decreasing. Use of waste aggregates seems to be alternative solu­tion. The aim of studies was to examine possibilities of repeated use of building by-prod­ucts and .y-ashes for construction of road subbases.

A new mathematical model for complicated machine constructions dynamic pro­perties calculation and optimization by DVA is proposed. The essence of the method is to introduce the few parameter models such that the differential equations for machines con­struction and there dynamic properties optimization can be effectively analyzed.
