Typical Arrangement of Links in Wall (If Asc > 0.02Ac):





Typical Wall Details:





Slab / Beam Starters From Wall:

Starters for half landing level slab and beam to be detailed along with wall drg as shown. Pull-out bars (Kwikastrip or similar approved) to be replaced with couplers if Ø > 16mm and extent of starters < 2 x lap length or 1.2m. 


These details can be used for floor slab and beams as well if the method of construction is slip form or jump form. 



Opening Trimming Detail:


Where,
Superscript as B means British code
Superscript as E means EC2

T L is Tension lap
T A is Tension Anchorage
C L is Comparation lap

Placement Plane and Orientation of shape driven rebar

-
Image
 This is meant as a brief overview of the options that exist during shape driven rebar placement. A shape driven rebar gets its geometry from a rebar shape loaded into the Revit project. This kind of rebar has a bar plane that contains all the bar geometry, segment planes perpendicular to the bar plane, which contain each segment, as well as an out of plane extent, which represents the end of the rebar set. To place such a bar in any 2D view, we need to position and orient it within the element and relative to the view plane. Here’s a simple example of placing the M_17 shape: • In a section view you can place the single bar in the current workplane, at the far end of the element (detected automatically) or at the near face of the element o Placing a single bar in a section like this, at the near cover reference, will show a warning that the bar is not visible • When placing a set in this section, the result is the same, regardless of the placement plane setting Placement orie...

Standard Shape Codes for UK detailing

 Standard Shape Codes General Notes  The values for minimum radius and end dimensions, r and A respectively, as specified in Table B.1, shall apply to all shape codes.  The dimensions in parentheses are the free dimensions. If a shape given in this table is required but a different dimension is to allow for the possible deviations, the shape shall be drawn out and given the shape code 99 and the free dimension shall be indicated in parentheses. The length of straight between two bends shall be at least 4d, (see Figure 6 BS 86666). BS 86666, Figures 4, 5 and 6 should be used in the interpretation of bending dimensions. Notes  1 The length equations for shapes 14, 15, 25, 26, 27, 28, 29, 34, 35, 36 and 46 are approximate and where the bend angle is greater than 45º, the length should be calculated more accurately allowing for the difference between the specified overall dimensions and the true length measured along the central axis of the bar. When the bending angles a...

Best tips for Revit beginners

  10 Best practices for Revit beginners Autodesk Revit is a great BIM tool for architects, engineers, designers and contractors. Yet, a tool is as good as its user, and the full potential of modeling in Revit can only be understood through a deep understanding of its various functions. Here are some important tips to help you make the most of Revit and speed up the modeling process. 1. Move from 2D, think 3D One of the biggest challenges with Revit is to move from 2D thinking to 3D thinking. Both professionals and students that came in my Revit classes during the past years were comfortable with how they did things and didn’t understand why change is needed. I must admit that when I started with Revit, (10 years ago) I did exactly the same. I was still thinking in a 2D Construction Document way. I was looking for a way to do the things I was used to, rather than adopting a new way of working. But eventually, I realized the full potential of the BIM process and technology and...
