ICT in Prefabrication & Precast Housing An SE CAD Case Study 7 th Industrialized Building System (IBS) Roundtable Workshop LIEW YONG SEONG B.Eng. (Hons.), M.Eng., MIES, MSSSS Advance Contech (Singapore) Pte. Ltd.
Outline What is SE CAD? It’s been a long way – the SE CAD story To maximize repetition through standardization & serialization What’s ahead?
Criteria For Residential structure Does NOT rely on proprietary system / components Centralize database: Eg. Joint details ○ Centre reference for tested joint details for beam-wall, beam- column, etc. Built in proven and tested precast components database of beam, column etc Serialize name of structural members for easy reference, order placing, production and site control, which is also third-party database friendly Extendabie – energy saving study, virsualization etc Super user friendly – for average user to be productive and expert in doing precast/prefab design.
centralized, reusable knowledge-base and an advanced engineering IT solution that streamlines construction processes! Goal : A TOTAL Prefab/Precast Solution for Housing!
To maximize repetition through standardization & serialization Structural Steel Better standardization Steel Database Universal Naming Convention Efficient Reference, Design, Checking, and Logistics
BEAM CAGE CODE J/U/P 2 3 6 1V Cage series Width of Beam Depth of Beam Ref. No. or Ref. No. with alphabet indicating type of stirrups Ref. No. indicating type of main reinf. Suffix
CAGE SERIES J Series - Light cage where cage reinforcement are used only for beams with clear span >1.5m. - J Series is fully shop fabricated with main bars. U Series - Standard cage where cage reinforcement are generally used for uniformly distributed loading condition. - Also applicable to light point load condition as specified in the details. P Series - Standard cage where cage reinforcement are generally used for point load condition. - Also applicable to uniformly distrbuted loading condition as specified in the details.
SUFFIXES S – For one span beam (Discontinuous at both ends), or for beam with depth difference from adjacent beams. Eg. J3612S / U3612S / P3612S V – For tapered beam and for U & P Series only. Eg. U3621V / P3621V (300X600 – 900) T – For 1 st storey beam tying column / wall (column / wall at one end or both ends). Eg. U3621T / P3612T B – For beam with non-standard width. Eg. J3612B / U3612B / P3612B D – For beam with non-standard depth. Eg. J3612D / U3612D / P3612D H – For beam using H bar stirrup cage. Eg. U4649H
BEAM CAGE – J SERIES J SERIES – Main Reinforcement & Stirrup
BEAM CAGE – U SERIES (1 or 2 layers bottom reinforcement) ( 3 layers bottom reinforcement) U SERIES – Main Reinforcement & Stirrup
BEAM CAGE – P SERIES P SERIES – Main Reinforcement & Stirrup (1 or 2 layers bottom reinforcement) ( 3 layers bottom reinforcement)
BEAM CAGE – “0” CAGE for U & P Series (ONLY STIRRUP CAGE) (Main reinforcement are shown in connection details)
BEAM CAGE – T13 BAR MARKED h FOR U OR P SERIES INCLUDNG “0” CAGE TYPICAL U OR P SERIES CAGE
