Abstract
The article discusses the fragile destruction of building materials during strong earthquakes, the features of the macroseismic effect of cracking expressed in the protective coatings of buildings; it is recommended to optimize the composition based on polymer by composition that increases the crack resistance of plaster solutions. In particular, the visualization of macroseismic parameters is given on the example of the survey of the epicentral zones of the Tashkent (2008), Cannes (2011) and Marzhanbulak (2013) strong earthquakes that occurred in Kyrgyzstan and Uzbekistan. Possible directions of crack development and density of their distribution over the macroseismic area are analyzed. It was revealed that the vulnerability to micro-destruction of types of protective materials is proportional to the seismic intensity and is mainly due to the intensity of seismic vibrations.
Highlights
The urgency of the problem of long-term development of earthquake-resistant protective coatings, based on macroseismic estimates of real strong earthquakes, required the substantiation of some new scientific provisions
The increase in the macroscopic stability of these materials significantly affects the macroseismic parameters when examining the epicentral zones of strong earthquakes
We have studied the effect on the macroseismic parameters of visually detected parameters of the fracture density of protective coatings in the zones of moderate fluctuations of several strong earthquakes that occurred in the recent past in Kyrgyzstan and Uzbekistan
Summary
The urgency of the problem of long-term development of earthquake-resistant protective coatings, based on macroseismic estimates of real strong earthquakes, required the substantiation of some new scientific provisions. The use of new types of earthquakeresistant protective materials, improving the strength of enclosing structures, lead to a reduction in the cost of repair and restoration work of buildings and an increase in indoor comfort. As the practice of construction works in Uzbekistan over the past 25 years has shown, the use of effective acoustic materials, similar in structure and production methods to earthquake-resistant materials, increases the culture of construction, the comfort of living conditions. Local deformations in their plane are significant for prefabricated and monolithic structures
