Modeling of operation of cities and their transportation systems is a multi-component challenge composed of various data and decision options. Improvement of this analytical mechanism will make it possible to save the resources invested into development and operation of transportation and urban planning solutions.The mathematical modeling solution proposed by the author helps identify both predictable and accidental features of composite engineering and transport solutions. Assessments of the intensity of traffic, road capacity, speeds, parameters of geometrical elements, cost of construction and operation are also possible.Any thorough analysis requires specialized algorithms. Modeling of traffic streams in terms of the safety of the road motion reveals bottlenecks and dangerous areas to improve the traffic arrangements, or organization of the road motion.Cities and urban bridge crossings and their environment represent complex systems of interaction and mutual influence. Therefore, the mathematical model designed and developed by the author is based on the most relevant urban planning theories.

The co-authors consider the design solution developed for a panel residence building, type series 1-115, and provide a description of the emergency destruction of structural elements of a 9-storey panel residence building of this type (built in 1979), following a gas explosion. The overall length of the building is 86.4 m; its width is 12 m. The structural system in this building represents a longitudinal wall. Its external longitudinal walls are wade of ceramsite concrete, while its interior walls are made of concrete. Its reinforced concrete hollow slabs rest on the longitudinal load-bearing walls. The transverse walls of staircases are made of concrete blocks. The strip foundation supports the load-bearing walls of the building. The epicenter of the explosion was located in the kitchen on the eighth floor of the building. The kitchen was immediately adjacent to the staircase of the building. Partial destruction of the building followed the gas explosion. Exterior walls of its eighth and ninth floors and the attic were destroyed. Panel buildings designed in pursuance of the longitudinal structural system are more vulnerable to explosive loads compared to buildings designed to the cross-wall structural system, where bearing slabs rest on three interior walls. Thus, all slabs rest on each of the three internal walls of the building on both sides. In the buildings designed to the longitudinal wall structural system, slabs rest on the two walls, one of which is external. The article is based on the report following the inspection of the technical condition of the building, undertaken subsequent to its emergency destruction.

Defects of multi-layer brick masonry exterior walls

The article discusses possible defects of exterior walls of buildings that can occur in a multilayer brick masonry. The article is based on the inspection materials of the school building located in Bronnitsy, Moscow Region. The reasons of brick masonry defects are considered and analyzed. An external wall strength calculation of the stairwell of the building is given, confirming the reasons for the formation of defects in the masonry. The static calculation results of the exterior wall of the building stairwell revealed the presence of tensile forces in the zone of window sill of the lower window opening of the exterior wall of the building. The calculations of masonry tensile showed that load bearing capacity of the masonry in window sill zone is not provided. Thus, the calculation is justified for cracks in the window sill area of the calculated wall. The appearance of hairline cracks on the outer face of a decorative protective layer multi-layer masonry is due to the thermal deformations, the manifestation of which is enhanced by the presence of the layer of effective insulation located behind the layer of masonry and embarrassing action of rigid ties on the development of thermal deformations.
