Low Carbon Design Of The Frame Structure

In recent years，more and more topics about reducing greenhouse gas emissionwere discussed on the international. The building could accounts for36%of total CO2emission in many industrial countries. So reducing CO2emission is urgent. Manycountries have studied the building environment, the whole life cycle of buildingevaluation system is one of the common method. This paper will discuss the energyconsumption of materials based on the system.The energy consumption of materials in each stage of construction activities hasrelation with the amount of building materials. If decreasing the amount of materialsin the beginning of the structure design, which will influence the CO2emission ineach stage of construction activities. This paper will analyze the design how toreducing the amount, the content including the following:(1) Use the different strength of the steel bar and concrete to design the beams,columns and foudations and calculate the CO2emission on the same building.(2) Simulate a single layer frame structure to evenly divide the length of thelongitudianal form different number of grid n. Use the standard formula to designplate, beam and column. And adjust the fomula, which contain n. Then find therelationship between n and the dosage of steel per unit area. Finally know the changeof CO2emission.(3) Simulate a single layer frame structure to design the element under horizontalload. Find the relationship between storey m and the dosage of steel per unit area andthe change of CO2emission.(4) Calculate the function about the n and internal forces of foundation and theCO2emission.
