SADS Modelling Services

 SADS is widely adopted to be the major structural analysis software in Hong Kong due to its comprehensiveness and user-friendly interface. 


By adopting a programmed algorithm, we can cater the tedious input procedures of SADS so as to drastically shorten one of the major time constraints in local consultant firms. 


Through the algorithm, we can also easily adopt yield line division of slab loadings so as to accurately and efficiently assign two-way slab loadings on adjacent beams.

What we need:

 

1.    Framing Plan in CAD file;

2.   Loading Key Plan with Loading Types described


 

What we provide:

 

1.    .bck file with all essential inputs in SADS format;

2.    .edb file in ETABS for your further action, if requested;

3.    Summary Tables of all structural elements and loadings input

Tentative Rock Head / N200 Levels Detection

In foundation designs, the tentative founding levels of bored piles, socketed H-piles, driven H-piles and other common types of piles are all based on the rock head or SPT N200 Contours.


By adopting a programmed algorithm, we can analyze the rock head contour provided and assign the most accurate tentative levels for the piles required.

What we need:

 

1.    A .srf file of the contour which is generated by Surfer

2.  A list of piles with global coordinates and diameters (Example)


 

What we provide:

 

 1.  A list of piles with tentative levels found 

Rock Cone & Soil Mass Calculations

In foundation designs, ultimate uplift forces are usually countered by the rock cone and soil masses.


By adopting a programmed algorithm, we can calculate the volume of rock cone shared by each pile mathematically.

What we need:

 

1.   A list of piles data with essential data; and

2.  Boundary line Information (Example)


 

What we provide:

 

1.    A list of piles with soil and rock mass shared; 

2.   Detailed calculation & chart illustration for each pile (Example);

Advanced Piles Modelling in SAFE

For the common practice of foundation design, piles are usually modeled as point springs in gravity analysis, while in lateral analysis, they are analyzed using a separated software, such as SAP2000, Piglet, etc. The following summarized the potential drawbacks: 


1.    Omitted Gravity Pile Head Moments

2.    Omitted Portal Frame Up and Down Reaction Forces

3.    Tedious Input and Output in pile iterations


By adopting a programmed algorithm, we can easily import the entire length of piles into a SAFE model, so as to incorporate gravity and lateral models into a single model for much better convenience. 

What you may provide:

 

 1.    Details of the drill hole log for lateral springs assignment 


 

What we provide:

 

 1.    A easy-to-use programmed spreadsheet for your further use 

R.C. Tables Generation

R.C. Tables are widely adopted in the structural industry to illustrate the types and number of reinforcements adopted in different concrete structures, such as beams, slabs, columns and walls. 


By adopting a programmed algorithm, we can efficiently and comprehensively transfer the SADS design outputs into excel tables.


Through the algorithm, we can also cater different kinds of special requirements, such as torsional links on edge beams, etc.

What you may provide:

 

 1.    A .bck file in SADS with all essential elements designed 


 

What we provide:

 

1.    R.C. Tables of the required types of elements;

2.    Summary Tables of all errors or special types of elements;

3.    Programmed Spreadsheet for your further use, if requested.

Tailor-made Products

Every engineering project is unique and full of characteristics, thus, special requirements often appear in every aspect of design. 


Our company is always willing to embrace new challenges and provide up-to-date computation and programming service to cater your particular needs. 

What you may provide:

 

 1.   A list of requirements on the programmes required. 


 

What we provide:

 

 1.    A easy-to-use programmed spreadsheet for your further use
