Design of reinforced concrete cores and walls in Axis. VM X 5 RC 5 module

Reinforced concrete cores and walls Reinforcement can be assigned to virtual beams and virtual strips: • Virtual beams can be used to design reinforcedconcrete cores with the assumption that sections remain approximately plane before and after loading. • Virtualstrips can be used by the designcheck of wall ends or wall segmentsconsideringpossiblebucklingfailuresof the wall between floors.

Defining reinforcement • Parameters for reinforcement and actual reinforcement can be specified in the dialog (Design check of reinforced concrete core/wall ) below. • This dialog can be opened after clickingon Define and check reinforcementbutton on Virtual beams and Virtual stripstabs, respectively. • On the page of Reinfrocement bars the steel material, the concrete material, the out-of-plane bucklingparameters(only in case of virtualstrips) can be specified and longitudinal reinforcement with certain diameter can be placed in the cross section.

Design check After selecting. Core/wallcheck tab, the programperformsthe verificationagainst bendingwith or without axial force based on the cross-section properties and reinforcement parameters.

Storeys Before definitionof actual reinforcement, stories need to be assignedof the virtual beams/strips. Using stories, more economical and efficient reinforcementcan be assignedto the virtualbeam that followsthe changein the internal forces. A storey needs to have intersectionwith the axis of the selected virtual beam/strip. The softwarefills the list of storieswith predefinedmodel stories if there any. The stories assigned to a virtual beam or strips does not necessarily need to be identical with the stories of the model.

Overall utilization On the overall utilizationtab, design results of reinforced concrete cores calculated with virtual beams and design results of wall ends/segmentscalculatedwith virtual strips can be summed. It may be necessary because the Nx-My. Mz strength interaction diagram of cores is generated without considerationthe loss of stability of compressed wall ends and inner wall segments. The program supports the use of various summationrules as it can be seen in the following figure. The combinationrule to calculateutilizationfor the selected virtualbeam – virtualstrip pair can be definedbelowthe list. The different combination rules are available : 1. η = max(η 1, η 2) 2. η = (η 1)a + (η 2)b

Display If storiesand actual reinforcementare assignedto the virtualbeam/strip, the cross sectionwith reinforcement will be displayedtogetherwith circleson the axis of virtualbeam/stripindicatingthe boundariesof the defined stories. The name of the actual reinforcementassigned to the storey is displayedclose to the middle of the storey on the axis of the virtual beam/strip.
