We need to get the service load reactions at each girder for the bearing design. Is there an easy way to summarize all the reactions in one table? We have 7 spans with 9 girders per span so it is unwieldy to pull them out one at a time.
Also, the live load reactions are stated to be per lane without impact. Do they include a multiple presence factor of 1.2 for a single lane?
Currently there is no solution to summarize all the reactions in one table.
You should be able to create a spreadsheet and get the reactions under each bearing.
Generally the Live load reaction shown in the conspan output is for the whole support and whatever LL reaction the user gets for the whole support is per lane and is not multiplied with DF and IM factor. To get the unfactored LL reaction for each bearing location just multiply it by appropriate Number of lanes , DFs based on exterior and interior beams .
Its left to the user to decide whether he/she wants to multiply with the DF and IM factor . Some cases the user wants the reaction with DF only and in some cases both IM and DF.

Regarding the Multiple presence factor , if the user is inputting the LL reactions manually then he has to multiply the MPF with the LL reactions and then input the values in RC pier .When the user generates the Live load reaction then the program multiplies the LL reactions with the MPF in the LOADS TAB itself.

Thanks for the answer.
Hello,
I would like to tell you something related to it
you can use a spreadsheet program like Microsoft Excel or Google Sheets. You would need to input the individual reactions for each girder into the spreadsheet and use formulas to calculate the total reactions for each span. You can then use the spreadsheet to generate a table that summarizes the reactions for all the girders. Dashboard Anywhere
As for the live load reactions, it's best to consult the specific design code or standard being used for the project to determine the correct multiple presence factor. However, as a general rule, live load reactions per lane without impact do not include the multiple presence factor. The multiple presence factor is typically applied to the total live load on the bridge to account for the possibility of multiple vehicles being on the bridge at the same time. hope so it is useful for you .
Thank You. That is helpful.
