Atkins ETABS Manual
Use that form to add, modify, or delete material properties. In the following sections some key features will be addressed. Table of Contents 1. The interaction surfaces are developed for 8 different ratios of reinforcing steel area to pier area, which spans between the maximum and minimum ratios as specified in preferences. This type is generally recommended unless the user is confident mmanual the realistic behaviour of the member.
If clicked again for the same selected area, they will be divided in half again, and so on. Therefore the vertical spring stiffness may be expressed as: Shear design will be performed same as uniform reinforcing section. If the shell element mesh is refined, consider extending the beam into the wall at least one shell element to model proper fixity. Since 3-D representation is not used for typical floor plan and elevation in Atkins Dubai, this option will not be covered in this manual.
It should be noted that when SRSS method is used for directional combination of responses, the response would be independent of the excitation angle. For example, specifying a meshing of 2 by 8 means that the selected area will be meshed into 2 areas along the x-axis. In that case you would input a scale factor equal to the product of the scale factor to convert the spectrum to the appropriate units and the scale factor to scale the response spectrum base shear to the appropriate level.
In planar walls, the minor axis moment effect will be ignored. If the meshes on common edges of adjacent area objects do not match up, automated line constraints are generated along those edges.

It is assumed that the user of this manual has a good command of ETABS and is familiar with the following codes: Reinforced Concrete Design Module 9. The angle will be measured in wtkins counter clockwise direction for the x and y-axis. In general, slab elements may be drawn manually, but this is time consuming and may lead to unrealistic results if local axes of slabs are different or unsuitable mesh sizes are used.
Definition and Sizing of Elements 3. Base material type needs to be defined at this stage, which can’t be revised in the design overwrites form later. Various load combinations shall also be defined accordingly.

Structural Department, Atkins Dubai Year: One more points can be selected for this type of meshing. The program will report the demand I capacity ratio and required shear manial for the governing load combination. A positive angle appears counter clockwise as you look down on the model. Choose Create All Cases, so that all design wind load cases are determined as per Fig.
However, in some cases, a lower level may be chosen. This ztkins section is applicable to two and three dimension shear wall systems. For membrane and shell type elements, different membrane or bending thickness may be defined based on the actual behaviour of the slab system as shown in the following example. The size of the meshed areas will be uniform along a given direction. These warnings may be removed by reshaping the objects, defining appropriate boundary conditions I supports or any other ettabs action that ensures a sound analytical model.

A self-weight multiplier of 1 means that the full self-weight of the structure is included in that load case. This option meshes the selected area into smaller areas. These loads are generally calculated etsbs recognized wind tunnel testing laboratories based on the dynamic properties of the structure as modelled during the preliminary or concept design stages.
If the selected line passes through more than one area, all of the areas will be meshed. Posting Komentar Jika anda menemukan masalah pada link download atau anda punya saran, silahkan berikan komentar.
There are two important items that should be checked: If a wall pier is made up of both line and area objects, assign the pier label to the line and area objects separately. The gross section area based on UBC 97 Clause
