Axial Load to Columns

[bkrclk]

In the earthquake code, the axial load can be at most 0.5*Ac*Fck, but in the idecad calculation reports, it does not give a warning even though the loadings and the incoming axial loads are greater than 0.5*Ac*Fck. Axial load on SB208 and SB209 Columns was given in t. When we do 0.5*Ac*Fck, 350 t force should come, which is more than 350 t. Now you can say that the regulation says vertical loads and loads that combine earthquake effects, that is, loads like g+q+e or 0.9g+Ex, but why 1.4g+1.6q loading is shown in the calculation report.

[b ]You are looking at another report.[/b] The axial load is checked and the user is warned if it exceeds. The place where this control is shown is not the report in the picture you added. The report in the picture is for bending reinforcement design loadings. The axial force control is not given in this report. The Nd Column in this report is the design axial force (Axial force consisting of the loading combination that produces the most reinforcement.) Maximum axial force control in columns is given in the following report According to Nmax<=0.5*Ac*Fck specified in TDY2007 item 3.3.1.2 for vertical+earthquake loadings For increased vertical loads, it is carried out according to the limit value of Nd<=0.9*Ac*Fcd specified in Article 7.4.1 of TS 500. The controls performed are reported under the title of Column Axial Force Control.
