Moreover since the Wind consultants generally carry out their calculations at the center of the diaphragm of each floor, it is recommended that these points are taken in locations where are as close to the center of mass of diaphragm as possible. Refer to the discussion below for further clarification.
However, the results of response spectrum analysis may be scaled to the Equivalent Static Force Method as per Clause Atkinns to Section The self-weight and imposed dead loads shall be defined separately as explained below: The primary objective of this document is to make sure that ETABS is used consistently by the structural engineers in Atkins office in Dubai ettabs terms of:.

Selecting this option will mesh the area horizontally and vertically using the selected point at the edge as reference. 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.
This may be caused by adjacent atkinw o forming a discontinuous mesh, a free-free end support etc.
The drift and accelerations shall be checked accordingly. This automatically accounts for torsion in 3D wall piers. The effective wind speed shall be determined as per Clause 2.
Leg 2 The pier is broken up into four legs labelled Leg 1 through Mamual 4.
If you are running response spectrum or time history analysis, use ritz-vectors. In general, slab elements may be drawn manually, atoins this is time consuming and may lead to unrealistic results if local axes of slabs are different or unsuitable mesh sizes are used. Note that the maximum number of iterations specified is the maximum number of additional analyses after the first analysis is run.
Five percent is the default and is entered as 0. Make sure that appropriate layers are selected to be imported. By default the bottom story is the base of the building and the top story is the uppermost level of the building. Base material type needs to be defined at this stage, which can’t be revised in the design overwrites form later.
The stiffness of these springs may be calculated based on the maximum allowable axial force and settlement of the pile. Without Auto-line constraint Case2: Member design will be based on end-face moments not centre-point.
User can vary vertical rebar diameter and spacing [ and details.

The section property modifiers may be assigned to each section at this stage or later. This option meshes each selected area at any location where it intersects a visible grid line, regardless of the coordinate system associated with the grid line. J Shear stress is not limited to the requirement of high strength concrete.
Therefore, the Equivalent Static Force Method shall be initially used. A self-weight multiplier of 1 means that the full self-weight of the structure is included in that load case. Then ETABS will automatically calculate the atkinz loads acting on each story level and use it in the static analysis processor.
Different sized shell elements provide different fixities and thus, different analysis results. Determine the mankal values for the structure manuao per Clause 6.
In general triangular plate-bending element, with shearing deformations, produces excellent results. It should be noted that this is a necessary but not sufficient condition to ensure a sound modelling and analysis.
The Poisson’s Ratio and Coefficient of thermal expansion shall be taken as 0. The exposure type is generally taken as Exposure C for Dubai, but should be verified with the wind specialist accordingly.
