EX. US-1 Plane Frame with Steel Design
After one analysis, member selection is requested. Since member sizes change during the member selection, another analysis is done followed by final code checking to verify that the final sizes meet the requirements of the code based on the latest analysis results.
EX. US-2 Area Load Generation on Floor Structure
A floor structure (bound by global X-Z axis) made up of steel beams is subjected to area load (i.e., load/area of floor). Load generation based on one-way distribution is illustrated in this example.
EX. US-3 Soil Springs for Portal Frame
A portal frame type steel structure is sitting on concrete footings. The soil is to be considered as an elastic foundation. The value of soil subgrade reaction is known from which spring constants are calculated by multiplying the subgrade reaction by the tributary area of each modeled spring.
EX. US-4 Inactive Members in a Braced Frame
This example is a typical case of a load-dependent structure where the structural condition changes for different load cases. In this example, different bracing members are made inactive for different load cases. This is done to prevent these members from carrying any compressive forces.
EX. US-5 Support Settlement on a Portal Frame
This example demonstrates the application of support displacement load (also known as a sinking support) on a space frame structure.
EX. US-6 Prestress and Poststress Loading
This is an example of prestress loading in a plane frame structure.
EX. US-7 Modeling Offset Connections in a Frame
This example illustrates modeling of structures with offset connections. Offset connections arise when the center lines of the connected members do not intersect at the connection point. The connection eccentricity behaves as a rigid link and is modeled through specification of MEMBER OFFSETS.
EX. US-8 Concrete Design for a Space Frame
In this example, concrete design is performed on some members of a space frame structure. Design calculations consist of computation of reinforcement for beams and columns. Secondary moments on the columns are obtained through the means of a P-Delta analysis.
EX. US-9 Modeling Slabs and Shear Walls Using Finite Elements
The space frame structure in this example consists of frame members and finite elements (plates). The finite element part is used to model floor slabs and a shear wall. Concrete design of an element is performed.
EX. US-10 Finite Element Model for a Rectangular Tank
A tank structure is modeled with four-noded plate elements. Water pressure from inside is used as loading for the tank. Reinforcement calculations have been done for some elements.
EX. US-11 Response Spectrum Analysis of a Frame
Dynamic analysis (Response Spectrum) is performed for a steel structure. Results of a static and dynamic analysis are combined. The combined results are then used for steel design.
EX. US-12 Moving Load Generation on a Bridge Deck
This example demonstrates generation of load cases for the type of loading known as a moving load. This type of loading occurs classically when the load-causing units move on the structure, as in the case of trucks on a bridge deck. The mobile loads are discretized into several individual immobile load cases at discrete positions. During this process, enormous number of load cases may be created resulting in plenty of output to be sorted. To avoid looking into a lot of output, the maximum force envelope is requested for a few specific members.
EX. US-13 Section Displacements for a Frame
Calculation of displacements at intermediate points of members of a plane frame is demonstrated in this example.
EX. US-14 P-Delta Analysis of a Frame Under Seismic Loads
A space frame is analyzed for seismic loads. The seismic loads are generated using the procedures of the building code. A P-Delta analysis is performed to obtain the secondary effects of the lateral and vertical loads acting simultaneously.
EX. US-15 Wind and Floor Load Generation on a Space Frame
A space frame is analyzed for loads generated using the built-in wind and floor load generation facilities.
EX. US-16 Time History Analysis for Forcing Function and Ground Motion
Dynamic Analysis (Time History) is performed for a 3 span beam with concentrated and distributed masses. The structure is subjected to forcing function and ground motion loading. The maxima of joint displacements, member end forces and support reactions are determined.
EX. US-17 User-Provided Tables
The usage of user-provided steel tables is illustrated in this example for the analysis and design of a plane frame. User-provided tables allow you to specify property data for sections not found in the built-in steel section tables.
EX. US-18 Stress Calculation for Plate Elements
This is an example which demonstrates the calculation of principal stresses on a finite element.
EX. US-19 Inclined Supports
This example demonstrates the usage of inclined supports. The word INCLINED refers to the fact that the restraints at a joint where such a support is specified are along a user-specified axis system instead of along the default directions of the global axis system. STAAD.Pro offers a few different methods for assigning inclined supports, and we examine those in this example.
EX. US-20 Generating a Structure in Cylindrical Coordinates
This example generates the geometry of a cylindrical tank structure using the cylindrical coordinate system. The tank lies on its side in this example.
EX. US-21 Analysis of a Structure with Tension-Only Members
This example illustrates the modeling of tension-only members using the MEMBER TENSION command.
EX. US-22 Time History Analysis for Sinusoidal Loading
A space frame structure is subjected to a sinusoidal (dynamic) loading. The commands necessary to describe the sine function are demonstrated in this example. Time History analysis is performed on this model.
EX. US-23 Spring Support Generation for a Slab on Grade
This example illustrates the usage of commands necessary to automatically generate spring supports for a slab on grade. The slab is subjected to pressure loading and analysis of the structure is performed.
EX. US-24 Analysis of a Concrete Block Using Solid Elements
This is an example of the analysis of a structure modeled using solid finite elements. This example also illustrates the method for applying an enforced displacement on the structure.
EX. US-25 Analysis of a Structure with Compression-Only Members
This example demonstrates the usage of compression-only members. Since the structural condition is load dependent, the PERFORM ANALYSIS command is specified once for each primary load case.
EX. US-26 Modeling a Rigid Diaphragm Using Control-Dependent
The structure in this example is a building consisting of member columns as well as floors made up of beam members and plate elements. Using the control-dependent command, the floors are specified to be rigid diaphragms for in-plane actions but flexible for bending actions.
EX. US-27 Modeling Soil Springs for a Slab on Grade
This example illustrates the usage of commands necessary to apply the compression only attribute to spring supports for a slab on grade. The spring supports themselves are generated utilizing the built-in support generation facility. The slab is subjected to pressure and overturning loading. A tension/compression only analysis of the structure is performed.
EX. US-28 Calculation of Modes and Frequencies of a Bridge
This example demonstrates the input required for obtaining the modes and frequencies of the skewed bridge shown in the figure below. The structure consists of piers, pier-cap girders and a deck slab.
EX. US-29 Time History Analysis of a Frame for Seismic Loads
Analysis and design of a structure for seismic loads is demonstrated in this example. In this model, static load cases are solved along with the seismic load case. For the seismic case, the maximum values of displacements, forces and reactions are obtained. The results of the dynamic case are combined with those of the static cases and steel design is performed on the combined cases.
