Response-2000 Assumptions

The first assumption in Response-2000 is the traditional engineering beam theory assumption that plane sections remain plane. This is appropriate for beams and columns that are more than, perhaps, 4 times their depth. The second assumption is that there is no significant transverse clamping stress acting through the depth of the beam. This is also an appropriate assumption for beams that are of a similar length to that above and produces conservative results. That is, if there is transverse clamping, the real strength of the beam will be higher than that predicted by the program. The third assumption is that the Modified Compression Field Theory (MCFT) can be used for biaxial stress-strain behaviour throughout the depth of the beam.

Using these three assumptions, the generally well known fibre model of sectional analysis is extended to include the effects of shear.

Papers on Shear Distribution Method

The methods used in Response-2000 since version 0.7.8 are a new invention that allow faster and more stable analyses than the previous state-of-the art, which was called "Dual Section Analysis." The following two papers describe this previous state-of-the-art. Currently, the only description of the new method is in the thesis, listed above. Papers are currently being prepared which will make this information more available.
