HELLO, EASY TO EVERYONE; WE HAVE AN EXISTING BUILDING AND WE WILL MAKE A REINFORCEMENT PROJECT BUT THE ADMINISTRATION WANTS US TO ANALYSIS DISTANCE IN TIME DEFINITION FIELD BECAUSE IT IS LESS THAN 15 KM TO THE NEAREST FAULT.

Time history analysis when the nearest fault is less than 15 km

Re: Time definition moment when the nearest fault is less than 15 km Hello; In the TBDY 5B section, the details of the single mode pushover analysis method are explained. In the pushover analysis, the modal displacement demand must be obtained in order to determine the performance point of the structure. This modal displacement demand is obtained using the horizontal elastic design spectrum that we used in the design. This topic is covered in 5B.3. However, as you wrote in 5B.3.6, it is not valid when one of the situations (a) and (b) and must be done according to 5B.4. When we examine 5B.4, it is written that to find the modal displacement demand of the earthquake, it will be obtained from nonlinear calculation in the time history. In this case, a modal capacitance curve in the time history can be obtained by using the modal single degree of freedom system. To do this, a spectrum curve is obtained by converting the acceleration records into a spectrum curve. An average modal displacement demand can then be obtained by scaling according to TBDY 2.5. This obtained modal displacement demand can also be used to find the performance point of the structure under pushover analysis. Here, the calculation of the modal capacity curve in the time history is explained, not the non-linear analysis in the time history. Non-indirect calculus in the time history is a valid method for all types of structures. Various sanctions are applied in approximate methods such as pushover analysis. 5B.3.6 has listed the conditions for these propulsion methods. The push method can be used in your project, but the performance point must be made according to the modal capacity curve obtained from the earthquake records. Using the command below you can generate a modal capacity curve using 11 sets of accelerometer records (22 accelerometer records in total). I would like to make one more addition. As push analysis is currently under development, this possibility is not used in the program as of version 10.20. At the same time, the possibility of nonlinear analysis in the time history has not been added yet. Best regards...
