What is envelope load combination Etabs?
When an envelope combination is defined manually, the maximum moment, shear, axial, and torsional response from all load combinations are superimposed on a single design process which generates an over-designed system with capacity for unrealistically extreme loading. envelope. design. over-designed-reinforcement. …
What is envelope load combination?
An envelope load is defined as a new combination for which the basic results (displacements, distributed forces, distributed moments and reinforcement moments) are chosen for a set of selected load cases and load combinations, such that for every element node the load case combination with the minimum, maximum or …
How do I delete a combination on Etabs?
The automatically generated load or result combinations can be deleted by using the “Edit Model – General Data” window. First, deactivate the “Create combinations automatically” check box.

What is the difference between load case and load pattern?
Load patterns are then applied through load cases to generate analysis results. A load case defines how load patterns are applied (statically or dynamically), how the structure responds (linearly or nonlinearly), and how analysis is performed (through modal analysis, direct integration, etc.).
What is the governing load combination?
Load combinations govern the cost of initial engineering, procurement, and construction, and the cost of ongoing engineering and maintenance.
