There are basically two options here:
- The use of rod eccentricities, see technical contribution Consideration of rod and surface eccentricities
- In the case of, for example, differently defined rod end joints in combination with different dimensions of offsets, the use of couplings or rigid rods may help, see Figure 1
AnswerIn RF-CONCRETE Members (RFEM) or CONCRETE (RSTAB), the offset is considered by default when determining the provided reinforcement.The difference between required reinforcement with and without offset is displayed when you open the Results navigator window:- A s, -z (top)- A s, + z (bottom)- A s, -z (top), comp.- A s, + z (bottom), comp.display results.In A s, -z (top), comp. and A s, + z (bottom), comp. the offset is included.See Figure 1.For the provided reinforcement in RF-CONCRETE Members or CONCRETE, the program considers the anchorage length for "straight" iron by default. The input can be found in the input window 1.6. See Figure 2.The anchoring length becomes from A s, -z (top), comp. and A s, + z (bottom), comp. determines. Thus, the offset is also included here.
Since program version 5.19, the eccentric load introduction can also be directly considered in RFEM by using the member loads (see Figure 1). The eccentric load introduction can be applied for the "Force" load type.
Alternatively (for example in RSTAB), you can also consider a connection with a rigid member to consider external concentrated loads that act eccentrically on the member. The rigid member is to be connected perpendicularly to the corresponding member. The length of the rigid member corresponds to the amount of the eccentricity (see Figure 2).
Alternatively, you can enter the torsional moment due to the eccentric load introduction as external loading (also for eccentric member loads). Thus, the eccentric action would be considered and the definition of a rigid member would not be necessary (see Figure 3).
