How do glass and steel affect modern architecture?
Steel frame structure is mainly made of steel, which is one of the main types of building structures. It has the following characteristics: light weight, high working reliability, good impact resistance and impact resistance, and high degree of industrialization. Because steel has good plasticity and toughness, it can be deformed greatly and can bear dynamic load well. Secondly, steel is an ideal elastic body with good uniformity and isotropy, which is most in line with the basic assumptions of general engineering mechanics. Therefore, the seismic performance of steel structure is better than that of reinforced concrete structure.

Reinforced concrete structure is a structure composed of steel bars and concrete. Steel bars bear tension and concrete bears pressure. Compared with steel structure, it has the advantages of durability, good fire resistance, steel saving and low cost. The invention of reinforced concrete appeared in modern times and is generally believed to have been invented in 1848. 1872, the world's first reinforced concrete structure was completed in new york, USA, and a brand-new era in the history of human architecture began. After 1900, reinforced concrete structures were widely used in engineering. 1928, a new reinforced concrete structure, prestressed reinforced concrete, appeared and was widely used in engineering practice after World War II. /kloc-the invention of reinforced concrete and the application of steel in the construction industry in the middle of the 0/9th century made it possible to build high-rise buildings and long-span bridges.

Humans have learned to make and use glass for thousands of years, but since 1000, it has developed relatively slowly as a building glass material. With the development of modern science and glass technology and the improvement of people's living standards, the function of architectural glass is no longer just to meet the requirements of lighting, but has the characteristics of dimming, heat insulation, safety (bulletproof, burglarproof, fire prevention, radiation prevention and electromagnetic interference prevention) and artistic decoration. With the continuous development of demand, the molding and processing methods of glass have also made new progress. At present, with the development of new technologies such as interlayer, tempering, ion exchange, glaze decoration, chemical thermal decomposition and cathode sputtering, the usage of glass in buildings has increased rapidly, making it the third largest building material after cement and steel.

The main variety of building glass is flat glass, which has the advantages of smooth surface, light transmission, sound insulation, heat preservation, wear resistance, climate change resistance and stable material. It is made of quartz sand, sandstone or quartzite, limestone, feldspar, dolomite, soda ash, etc. As the main raw material, it is crushed, screened, blended, melted at high temperature, shaped, annealed, cooled and processed.
