IRON+&+STEEL

Jean Bauza: Hello everyone Leydi paola Laverde: Hi, how are you? Carlos Lopez z: hi =D Jean Bauza: do you read and listen the activities? Carlos Lopez z: yeah, and you? Leydi paola Laverde: Yes, I did. didn't pay much attention to the podcast. I prefer the readig, and it was good. the reading about iron and steel was very interesting because I learned the advantages that both have over stone and brick. These methods provide far stronger and taller structures with less expenditure of material than stone, brick or wood. Jean Bauza: my opinion does not stand much of yours. but also mentions that since the nineteenth century on, the iron and steel has been a growing most important. and that in the twentieth century has been so fundamental that architecture can do now, even with these 2 great art materials. Carlos Lopez z: I Think the iron and steel are stronger and more verstile material than wood, stone and brick, it can take on any shape, allowing the development of more complex works, taller and stronger Jean Bauza: that is truth Leydi paola Laverde: That's right. Also, I learned about the characteristics of steel, is more uniformly strong, elastic, and workable, and its high resistance in all stresses (tension, compression and bending) can be closely calculated. Carlos Lopez z: yeah, addition, the development of iron and steel and building materials change the concept of wall brackets, since being stronger support better load allowing more open space both outside and within. Jean Bauza: that makes the steel be more attractive to work Carlos Lopez z: exact, and allows for more versatility when working Carlos Lopez z: however, the steel has its drawbacks at extremely high temperatures loses its strength, rust and is heavy. Jean Bauza: yes, that is right... Leydi paola Laverde: And, tell me, what is your opinion about the welding? Jean Bauza: this comes in the 20th century.made it possible to produced fused joints with less labor and material Jean Bauza: I think is really important know something about this. Leydi paola Laverde: I agree with Jean, this is a fundamental change in architectural technique, the effect of which cannot yet be estimated. Carlos Lopez z: yeah Carlos Lopez z: allows continuous welding on site, making stronger structures as well as a more efficient distribution of the loads from the structure to the floor. This technique also allows the development of large works such as bridges across rivers giant buildings such as the Taipei 101, among others. Carlos Lopez z: they think about the disadvantages of steel as a construction material?, ie, steel rusts Jean Bauza: yeah well depends on the situation sometimes you have to choose other materials Jean Bauza: aluminum is sometimes convenient for its water resistance, and that's good for exterior building Leydi paola Laverde: That's true. Also depends of the structure, sometimes is better to use another material than steel. Carlos Lopez z: I agree, but steel is the strongest material for the construction of large buildings because it is stronger both in compression and in tesion, so some esque coatings are used to make stainless steel, and stainless steel also Leydi paola Laverde: Well, it was a good conversation but we have to say goodbye Leydi paola Laverde: Take care Carlos Lopez z: bye, see you soon Jean Bauza: I enjoy this conversation but leydi have to make desing.good bye Carlos Lopez z: the same for you Carlos Lopez z: bye bye
