EX. UK-14 P-Delta Analysis of a Frame Under Seismic Loads

A space frame is analyzed for seismic loads. The seismic loads are generated using the procedures of the building code. A P-Delta analysis is performed to obtain the secondary effects of the lateral and vertical loads acting simultaneously.

This problem is installed with the program by default to C:\Users\Public\Public Documents\STAAD.Pro CONNECT Edition\Samples\Sample Models\UK\UK-14 P-Delta Analysis of a Frame Under Seismic Loads.STD when you install the program.

Example Problem No. 14

    STAAD SPACE EXAMPLE PROBLEM FOR UBC LOAD

Every input has to start with the term STAAD. The word SPACE signifies that the structure is a space frame.

    UNIT METER KNS

Defines the input units for the data that follows.

    JOINT COORDINATES
    1 0 0 0 4 10.5 0 0
    REPEAT 3 0 0 3.5
    REPEAT ALL 3 0 3.5 0

The X, Y and Z coordinates of the joints are specified here. First, coordinates of joints 1 through 4 are generated by taking advantage of the fact that they are equally spaced. Then, this pattern is REPEATed 3 times with a Z increment of 3.5 m for each repetition to generate joints 5 to 16. The REPEAT ALL command will then repeat 3 times, the pattern of joints 1 to 16 to generate joints 17 to 64.

    * columns
    301 1 17 348

Defines the members by the joints to which they are connected. Following the specification of incidences for members 101 to 112, the REPEAT ALL command is used to repeat the pattern and generate incidences for members 113 through 136. A similar logic is used in specification of incidences of members 201 through 212 and generation of incidences for members 213 to 236. Finally, members incidences of columns 301 to 348 are specified.

The beam members have prismatic member property specification (YD & ZD) while the columns (members 301 to 348) have their properties called from the built-in British steel table.

The DEFINE MATERIAL command is used to specify material properties and the CONSTANT is used to assign the material to all members.

Tip: You may see these values with the help of the command PRINT MATERIAL PROPERTIES following the preceding commands.

There are two stages in a static seismic load. The first stage is to define the code-specified load parameters along witht he vertical loads (weights) from whic the base shear will be calculated. The vertical loads may be specified in the form of selfweight, joint weights and/or member weights. Member weights are not shown in this example. It is important to note that these vertical loads are used purely in the determination of the horizontal base shear only. In other words, the structure is not analyzed for these vertical loads.

    LOAD 1

    SELFWEIGHT Y -1.0
    JOINT LOADS
    17 TO 48 FY -7.0
    49 TO 64 FY -3.5

This is the second stage in which the static seimsic load is applied with the help of a load case number, corresponding direction (X in the above case) and a factor by which the generated horizontal loads should be multiplied. Along with the seismic lateral load, deadweight is also added to the same load case. Since we will be doing second-order (PDELTA) analysis, it is important that we include horizontal and vertical loads in the same load case.

    LOAD 2
    UBC LOAD Z 0.75
    SELFWEIGHT Y -1.0
    JOINT LOADS
    17 TO 48 FY –7.0
    49 TO 64 FY –3.5

In load case 2, the static seimsic load is being applied in the Z direction. Vertical loads are part of this case, also.

    PDELTA ANALYSIS PRINT LOAD DATA

We are requesting a second-order analysis by specifying the command PDELTA ANALYSIS. PRINT LOAD DATA is used to obtain a report of all the applied and generated loadings.

    PRINT SUPPORT REACTIONS
    FINISH

The above commands are self-explanatory.
