SAP2000 gives two different interaction surfaces for a member cross-section. First one says, i) Caltrans interaction surface and second one is ii) interaction surface (which is based on design codes). Why are they significantly different ? I have attached a sample plots for review.

I am looking for P-wave and S-wave velocity profiles (Vs30) for different sites covered by Engineering Geological Database for TSMIP (EGDT) for Taiwan. The database provides the soil profile in graphical format and is difficult to extract.
Does anybody got some idea regarding the data? kindly...
I am looking for P-wave velocity (Vp) of all the recording sites of PEER NGA West 2 Database. Flatfile of the database only mentions Vs30 and not Vp. There is a relation between Vs, Vp and Poisson ratio. However, Poisson ratio of the recording site is not available.
Is there any way to get the...
I came across a term 'characteristic value of response spectrum' in the literature in relation to seismic design of structure. Can anyone kindly elaborate the meaning of this term used in earthquake engineering?
How can one find characteristic value of a design (acceleration) response spectrum ...
Dear All,
I have modelled an 'I' shaped shear wall in the building using section designer. After running the analysis(static) and while checking the design, the 'I' shaped section is automatically getting converted to rectangular member of different c/s and reinforcement. Can anyone know about...
Is it able to carryout pushover analysis with link element in SAP2000 ?
Does the non-linearity assigned to the link in SAP2000 works in case of non-linear static analysis (Pushover analysis) ?

Does anybody know the link of reliable Databases for earthquakes recorded in India ?
COSMOS gives a small number of earthquakes recorded in India. There is another database which contains a large indian number indian earthquake records, PESMOS, managed by IIT Roorkee. But the website is...
I am new in the Area of High performance concrete. I wanted to know that, "Is there any standard guidelines for mix design of High performance concrete for any part of the world ?"
I found one, ACI 211.4R-93 but is only focused on high strength. If there is no standard specification then how...
What is the meaning of null steps in SAP2000? How the null steps occur?
How can be the null steps occurring in the Pushover analysis be reduced so that the number of required steps be achieved?

I am doing similar works as the above thread. My first step is to design a Barrage. I am aware of hydraulic design part of it. I need any standard guiding document on its structural design part.

Dear all,
I am modelling Shear wall in SAP2000 to perform linear elastic analysis. I have provided shear wall at few selected location in the form of shell element.
The structure is 5 storey, 5*5 bay with 5m bay width and 3.5m storey height.
When the building is analyzed, some of the beam is...
On what conditions, Beams are designed as T-beams?
What is the difference on the response of beam designed either as rectangular or T-beam when subjected to seismic excitation?

If we do not apply plastic hinges to the beams and columns but we apply Non-linear stress-strain curve in the material property for concrete and reinforcement. Will the model going to consider the material non-linearity ?

I have been doing pushover analysis of a distributed mass 3D model with rigid floor diaphragm.
The model is 6 storied, 4x4 bay with 5mx5m bay width, 3.5m storey height OMRF building
My questions are
Is it possible to get negative base shear in pushover analysis ?
And why are the hinge...
Hi all,
I have been doing pushover analysis with the plastic hinge definition as per ASCE 41:13. The model is distributed mass OMRF model. 6 storied, 4x4 bay with 5mx5m bay width, 3.5m storey height.
I have uploaded the SAP file.
The problem is " I am getting a lot of null steps and only 3...
How can we get the Parameters like "P and V value from" and "Reinforcing ratio" and "Shear reinforcing ratio".
If there lateral load applied then what load case do we need to apply for the above parameters ?
I have attached the screenshot.

I have been checking the effect on model mass by modelling a simple cantilever column fixed at the base. I have given the self weight of the column as zero.
The lumped mass are applied in the free end in x,y and z directions. No additional loading is applied. Mass source is fixed as the element...
