Accurate Elastic Shortening Computation
Elastic Shortening, ΔfpES (S18.104.22.168.3)
The prestress loss due to elastic shortening of pre-tensioned members is taken as the concrete stress at the centroid of the prestressing steel at transfers, multiplied by the ratio of the modulus of elasticities of the prestressing steel and the concrete at transfer.
This is presented in Eq. S22.214.171.124.3a-1.
ΔfpES = (Ep/Eci) fcgp (S126.96.36.199.3a-1)
Modified wall Panel & Meshing
• Click the Draw menu > Draw Floor/Wall Objects > Draw Wall Openings command or button to add an opening to the wall.
• You can lock dimensions while in the Properties of Object form. Make sure that snap increments via Draw > Snap Options are in line with specified opening dimensions so that the exact dimensions as entered in The properties of Object form can be reflected in the model.
• Then, left-click anywhere on the wall object where the opening is to be drawn.
• 4. If step 2 above is skipped, you can repeat step 3 then move the mouse pointer to locate the top left corner of the opening, using the coordinate display as a guide. Move the mouse pointer and click the lower right corner of the wall opening to draw the opening. A window object can be located anywhere within a wall object.
Automated load combination
The same can be extended to deformations. If you look for the deformed shape of an envelope, it will show the extreme values of displacements at all the points and they may not occur simultaneously. As a consequence, you might observe openings in the mesh or between the structural elements. This doesn’t mean the model is incorrect.
It is suggested to analyze the deformed shape for a particular combination but not the envelope. But to get the maximum values of the displacement you can turn to the envelope.
Buckling & Push Over & P-Delta Analysis
BUCKLING -Linear (bifurcation) buckling modes of a structure can be found under any set of loads. Buckling can be calculated from a nonlinear or staged-construction state. Full nonlinear buckling analysis is also available considering P-delta or large deflection effects. Snap-through buckling behaviors can be captured using static analysis with displacement control. Dynamic analysis can be used for modeling more complex buckling, such as follower-load problems.
Pushover analysis features in ETABS include the implementation of FEMA 356 and the hinge and fiber hinge option based on stress-strain. The nonlinear layered shell element enables users to consider the plastic behaviors of concrete shear walls, slabs, steel plates, and other finite area elements in the pushover analysis. Force-deformation relations are defined for steel and concrete hinges.
P-delta analysis captures the softening effect of compression and the stiffening effect of tension. A single P-delta analysis under gravity and sustained loads can be used to modify the stiffness for linear load cases, which can later be superposed. Alternatively, each combination of loads can be analyzed for full nonlinear P-delta effects. P-delta effects are included for all elements and are seamlessly integrated into analysis and design.
Design of concrete structur
The seminar topic “Design of an RCC structure using ETABS”, starts with drafting a plan for building in AUTO CADD software. After completion of the drafting process, the design of the slab, beam, and column is to be done. The design of the columns, beams, and slabs (Two-way and one-way slab) has been done according to IS 456 norms. The procedure is as follows, starting with the data collection for the design of the particular building. In which the information like the type of the building, building plan, floor-to-floor height, plinth height, depth of foundation, BCS of soil, wall thickness, and assumed loading factors including floor finish, roof finish, live load, and dead load. The material to be used in the structure is to be defined too
Design of steel structure
PEB structure analysis
Pre-engineered buildings are generally low-rise buildings however the maximum eave height can go up to 25 to 30 meters. Low-rise buildings are ideal for offices, houses, showrooms, shop fronts, etc. The application of the pre-engineered buildings concept low -risers buildings is very economical and speedy. Buildings can be constructed in less than half the normal time, especially when complemented with the other engineered sub-systems.
3D Structure Modelling.
Fundamental to ETABS modeling is the generalization that multi-story buildings typically consist of identical or similar floor plans that repeat in the vertical direction. Modeling features that streamline analytical-model generation, and simulate advanced seismic systems, are listed as follows:
• Templates for global-system and local-element modeling
• Customized section geometry and constitutive behavior
Buckling & Push Over & P-Delta Analysis
Pushover is a static-nonlinear analysis method where a structure is subjected to gravity loading and a monotonic displacement-controlled lateral load pattern which continuously increases through elastic and inelastic behaviors until an ultimate condition is reached. The lateral load may represent the range of base shear induced by earthquake loading, and its configuration may be proportional to the distribution of mass along building height, mode shapes, or other practical means.
Buckling occurs physically when a structure becomes unstable under a given loading configuration, and mathematically when a bifurcation occurs in the solution to equations of static equilibrium. The two primary means for performing buckling analysis include Eigenvalue and Nonlinear buckling analyses. Buckling must be explicitly evaluated for each set of loads considered because, unlike natural frequencies, buckling modes are dependent upon a given load pattern. When evaluating buckling, any number of load cases may be defined, each of which should specify loading, convergence tolerance, and the number of modes to be found.
Design Of Retaining Structure
Pre-engineered building analysis
Pre-engineered buildings are generally low-rise buildings however the maximum eave height can go up to 25 to 30 meters. Low-rise buildings are ideal for offices, houses, showrooms, shop fronts, etc. The application of the concept of pre-engineered buildings to low-rise buildings is very economical and speedy. Buildings can be constructed in less than half the normal time, especially when complemented with the other engineered subsystems

Wind analysis of building (IS 875 Part 3)
the IS 875-3: 2015, the design wind speed for the location and the design wind pressure for the rectangular building with pitched roof can be solved using the equations below:
Design wind speed at height z (in m/s): Vz = Vbk1k2k3k4 (1)
Vb is theBasic wind speed, m/s
k1 is the Probability factor (risk coefficient) based on 6.3.1 of IS 875-3
k2 is the Terrain roughness and height factor based on 6.3.2 of IS 875-3
k3 is the Topography factor based on 6.3.3 of IS 875-3
k4 is the Importance factor for the cyclonic region based on 6.3.4 of IS 875-3
Seismic analysis on structure (IS 1893 2002/2005
Analysis and report
Once modeling is complete, ETABS automatically generates and assigns code-based loading conditions for gravity, the seismic, wind, and thermal forces. Users may specify an unlimited number of load cases and combinations.
Analysis capabilities then offer advanced nonlinear methods for the characterization of a static pushover and dynamic response. Dynamic considerations may include modal, response-spectrum, or time-history analysis. The p-delta effect account for geometric nonlinearity.
Given an enveloping specification, design features will automatically size elements and systems, design reinforcing schemes, and otherwise optimize the structure according to desired performance measures.
