Abstract
Досліджено можливість використання несучих будівельних конструкцій зі скляного триплексу. Наведено результати експериментальних випробувань скляних багатошарових колон з вертикальним розташуванням шарів. Встановлено, що внаслідок
нових архітектурних тенденцій скляні конструкції в елементах фасадів, перекрить,
мостів, басейнів набули значного поширення. Проте сьогодні вони обмежуються лише
малогабаритними плитами, самонесучими перегородками чи фасадними склопакетами,
що мають скоріше огороджувальну функцію. Це стильне і ефективне рішення з
планування простору в останні роки набуває все більшої популярності. Максимальна
легкість і освітленість приміщення, витончений зовнішній вигляд сприяють
використанню скла в оформленні інтер’єрів приміщень та фасадів будівель. Також ці
конструкції, окрім естетичної привабливості, мають і достатню міцність.
The possibility of using structural building structures from a glass triplex is explored. Are presented the experimental tests of glass multilayer columns with vertical arrangement of layers. The results of experiments are presented. It is worth researching the possibility of using structural building constructions from non-traditional materials. One of these materials is glass. It is established that new architectural tendencies lead to use glass constructions in elements of facades, blocks, bridges, basins became widely used. However, nowadays, these constructions are limited only by smallsized plates, self-supporting partitions or facade fiberglass windows, which perform a mostly fencing function. It is suggested to use a glass triplex as a bearing structure. In recent years this stylish and effective space planning solution is getting more popular. Maximum lightness and room illumination, sophisticated appearance, reliability. Triplex, in which several layers of glass are reliably connected with a polymeric film EVASAFE (Bridgestone, Japan). The matrix of the film is an eclaced (polimer with high-elastic moisture in a wide temperature range), which allows to hold back the debris of the glass structures, makes them more pliable in the bonding plane, increases their reliability by preventing the instantaneous spread of cracks to the depths of the cross-section. Also, these constructions possess a sufficient strength, in addition to the aesthetic appeal. In this article is considered. an experimental research of glass multilayer columns with vertical arrangement of layers. Two experimental prototypes, which were tested as centrally compressed rods with rigid fixing ends, were made for experimental study. The test was carried out on a hydraulic press PG-250, with the help of which applied an external load of N steps of 2.5 kN up to destruction. The shutter speed at each load level was 10 minutes. According to the results of experimental studies, the graphs of the bends of the columns were constructed depending on the external load and the graph of the dependence of the relative strains on the stresses.
