Dlubal RFEM : Concrete Edition

Model a concrete column by selecting nodes, applying a displacement vector for six feet, and connecting nodes with a line and member; define a parametric cross-section and view in 3D.

select the target columns, open edit selection, and rotate the column by ninety degrees to adjust orientation, then verify in isometric and top views.

Select the bottom notes to define the column node, open new support, and set the type to rigid (fixed). Finalize the fixed support for the columns in RFEM.

Learn to model the plinth beam by setting the base level, moving the plane to origin, switching top and bottom views, and adding single members with sections; review for problems.

Learn to solve beam modeling problems in rfem by checking grades, fixing line grade values, deleting incorrect beams, re-modeling the beam with the same section, and validating the plan.

Select all ground-level columns and verify they turn yellow. Copy them in the perpendicular direction with a 6-ft displacement, then extend to 11 ft by adding 5 ft.

Model a floor beam in Dlubal RFEM by setting the origin, editing line groups, and inserting points to define the geometry.

Model a concrete slab in Dlubal RFEM by creating a rectangular surface, setting strength and six-inch thickness, then dragging to position with boundary line options for triangular or circular slabs.

Model the staircase base beam by selecting a member, copying it in the opposite direction with a 0.75 distance, and extending to the next member.

Model the mid landing beam in RFEM, select its center, and copy it to the opposite side by using the copy option, entering the copy count, and confirming.

Model a staircase slab in the first half by creating a rectangular surface with 1.5 inch thickness, then define the rest with a polygon, and delete unused elements.

Return to normal visibility by using the view menu to cancel visibility and see each element.

Complete the staircase modeling in RFEM by selecting and copying beams, moving them in the z direction, and creating slabs with polygon and rectangular tools to finalize the model.

Switch display options from transparent to solid models for clearer viewing, and use display mode to toggle between wireframe and solid views.

Model the first floor by selecting elements, editing the selection, and using move and copy to adjust heights and positions, including reducing heights from 11 to 10 feet.

Model three more stories by selecting existing items and copying them to create three additional stories in the direction. Confirm with OK to save time.

Model stair head components in Dlubal RFEM by selecting, copying, merging joints, and adjusting heights, then create a six-inch concrete rectangular slab and consolidate the model.

Learn to set and view slab thickness in Dlubal RFEM by enabling thickness in the rendering settings, turning on thickness, and comparing empty versus included thickness in the solid model.

Insert and define load cases in rfem by creating cases, naming them (for example partition wall), assigning serial numbers, marking them active, and assigning dead load and live load types.

Select all slabs at once, set a surface load, and apply a negative magnitude to the slabs using insert, then verify with the graphic view.

Select the slab, right-click to edit the surface, and set its thickness to 5.5 inches or 5 inches to adjust the slab in RFEM and show the load.

Select partition wall surfaces at the levels, isolate surfaces with thickness from six to six point five inches, and apply a 15 percent partition wall load in the correct direction.

Select the beams with Ctrl, insert the B.W. load along the selected beams, choose line graphically, enter the value (for example -0.5), and apply the backload to the region.

Apply partition wall loads on plinth beams in rfem by selecting exterior and interior beams, inserting a graphic load, and setting it to 0.5 in the negative direction.

Reduce node size to improve model clarity in the Dlubal RFEM interface; adjust the size settings and confirm to see the model with nodes minimized for a cleaner view.

Learn to apply a floor live load in Dlubal RFEM by selecting surfaces, editing the case, inserting a surface load, and setting the magnitude before confirming.

apply live loads in Dlubal RFEM concrete edition for stairs by selecting the active category, setting the load to 7.5, and graphically applying a surface-to-surface load with the negative direction.

Apply the roof live load in RFEM by switching to light, selecting the required members, and applying a 33 percent magnitude across the chosen elements.

Apply wind load for positive load cases in the RFEM model by setting W X plus and W Y plus, and adjusting wind, topographical, and renovation factors.

Apply the negative wind load in RFEM by configuring WX minus and WY minus, following previous steps, selecting vertical walls, and verifying the resulting WX minus and WY minus loads.

Set up earthquake analysis in Dlubal RFEM by enabling autonomous dynamics, run natural vibration, spectrum, and nonlinear time history analyses, then review mass calculations, deformation, and eigenvalues.

Run the analysis and global area in RFEM by selecting calculate, monitor the progress as it computes maximum displacement and linear analysis, and note the completion.

Explore analysis results and deformation, toggle animation to see how forces evolve, inspect internal forces and stresses, and review support reactions and other results in the project navigator.

Learn to design concrete columns in RFEM using the concrete columns tool: select all relevant combinations and members, verify material and reinforcement details, and run the design calculation.

Review design results for columns in rfem, select each column to view cross sections, reinforcement details (longitudinal reinforcement and stirrups), and member schedules, and assess bending and design criteria.

Design all concrete members in one go in RFEM by selecting all load combinations, assigning reinforcement materials, and reviewing results for columns, beams, and slabs.
