STAAD Pro v8i Software is widely used in analyzing and designing structures – buildings, bridges, towers, transportation, industrial and utility structures. The feature is there just in case you want to take advantage of the rigid portion and reduce the bending moments on the beam.STAAD stands for Structural Analysis and Designing. It is not absolutely necessary to specify offsets. Please go to Help-Contents-Application Examples-British Examples-Example 7 for additional information. To convey this information to the program, you could specify an offset at the start face of the beam (as well as at the end face) with a value equal to half the depth of the steel section used for the column at that location. So, the distance from the intersection point to the connection point is not as flexible in bending as the rest of the beam, but is instead considered rigid (high stiffness). However, in reality, the connection between the beam and columns may be located at the two inner faces of the columns.
For example, if you consider a portal frame drawn using 3 lines like in a football goal post, the node at the start and end of the beam is usually specified at the intersection of the centerlines of the beam and columns. An offset is a way of saying that the point where a beam starts or ends is at some distance away from the node associated with that location. Member offsets do not change the cross section of members. You can perform “P-Delta analyze” as this is a non-linear case. Else during analysis it will give some error message. One most important thing is that you have to assign the seismic load cases as the first load case before defining any other load case. Else the structure will be analyzed only for seismic load cases. The loads due to self weight or member weight should be assigned in load case details also. Load combination option, in this case, should not be used as this is a non-linear case. Or you can create a different primary load case where you add these loads and then create another primary load case where you have to use the “repeat load case” option to combine the loads. You can do it either by adding those loads separately in the two different seismic load cases. You also have to add all other loads like dead load, live load or wind load. The load factor must be assigned as 1 to define that the load is acting in the positive direction. There must be two separate load cases to define seismic load in different directions. The seismic load may be applied in X direction or may be in Z direction. For this a new primary load case has to be created in which the seismic load has to be added. Next the seismic load has to be assigned to the structure. The "Include accidental load" option helps to determine the effects of accidental torsion to account for the uncertainties in terms of centre of mass or centre of rigidity as there position can not be properly located.

You can select the code you want to follow. The weight of the floor can be defined using the floor weight option. The load coming from walls can be defined under member load option. If there is any load at the nodes you can define it by joint load option. The self weight option defines the self weight of different members. It is needed to calculate the total weight of the structure to calculate the “base shear”. Next you have to define the seismic weights.

Also in the technical reference manual in section 5.31.2.5, you will find some information regarding these. In IS-1893 the corresponding values are given.
In this particular part, those parameters like zone factor, performance factor or the soil type have to be defined to calculate the “Response acceleration coefficient”. On basis of those factors using the standard formula, defined in any standard code, the seismic load is calculated. To calculate the seismic load acting on the structure, there are different parameters which should be defined at first. First you have to define the seismic load and then you have to assign the load to the structure. To assign a seismic load in a structure there are two steps.
