What is load patterns in Etabs?
A load pattern is the spatial distribution of a specific set of forces, displacements, temperatures, and other effects which act on a structure. Any combination of joints and elements may be subjected to loading and kinematic conditions. Each load pattern is assigned a design type (DEAD, WIND, QUAKE, etc.)
What are load cases?
A load case is a set of loads and boundary conditions used to define a particular loading condition. You can use a nonzero scale factor to scale the magnitude of individual loads and boundary conditions within a load case. You may include a load or boundary condition only once within each load case.
What is a load pattern?
The load pattern properties specify how the simulated user load is adjusted during a load test. The load pattern is a component of a scenario. The scenarios, together with their defined load patterns, comprise a load test. In all Load Patterns, the load that Visual Studio generates is a simulated load of virtual users.
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 pattern live load factor?
The pattern live-load factor (Pllf) is intended to account for variability in the live-load arrangement on a structure. Since live-load pattern is not automated, Pllf approximates its design effect. While this does affect design moments, analysis moments are not affected.
What is load combination?
A load combination results when more than one load type acts on the structure. Building codes usually specify a variety of load combinations together with load factors (weightings) for each load type in order to ensure the safety of the structure under different maximum expected loading scenarios.
What are load combinations?
Is 1893 a load combination?
For IS 1893:2016, the maximum load combination factor is 1.5 and for NBC 105:1994 the maximum load combination factor is 1.3.
What is a load combination?
How do I export my Etabs load combination?
Within Model A, open the load-combinations definition table and export it to Excel by selecting Edit > Interactive Database Editing > Model Definition > Load Pattern Definitions > Response Combinations > Table: Combination Definitions. Within Model B, select the same database table as described previously.
