Flat slabs in contemporary buildings are most commonly supported by rectangular cross-section columns. Research of columns for punching is rather narrow. The purpose this work was the experimental research and adjustment their design method. Reinforced concrete 6 cm thickness without transverse reinforcement were used as testing specimens. During tests load on slab transferred using stamps. Sid...

Background: Traditionally, cool pavements have been designed as reflective, evaporative, etc. Though the reflective reduce pavement surface temperature significantly, they increase glare, thermal burden on pedestrian traffic, and of nearby buildings. In case evaporative pavements, absence water, reduced inertia solar reflection result in a higher temperature. As result, there has pressing need ...

A simple method is proposed to describe the propagation of electromagnetic waves in magnetized uniform plasma slabs. Using this method, the reflection, absorption and transmission coefficients of such plasmas for right-hand circularly waves are studied and the effects of the continuously changing external magnetic field on the power of the electromagnetic waves propagated in magnetized plasma s...

Water-cooling plays a major role in extracting heat from both the mold and solidifying metal during the continuous casting of steel and aluminum alloys and is characterized by complex boiling phenomena. Heat extraction rates during water-cooling, which have strong dependence on the metal surface temperature, can rapidly change with time as the strand cools down. Consequently, uncontrolled cooli...
