Steel & Concrete (SC) Structural Design is a consulting engineer firm and provides commercial 3-D model finite element analyses (FEA) in Civil/Geotechnical/Marine/Mechanical/Mining/Structural/Transporation engineering areas. SC also provides detailed structural design and construction drawings for building/bridge/tunnel structures.

----SC's FEA services cover the analyses of linear and nonlinear (material and geometrically) static/dynamic(vibration and transient); moving load/construction sequence; soil-structure interaction; thermal stress/thermal conduction/convection; concrete shrinkage/creep/crack; steel relaxation/fatigue/erosion, earthquake spectrum/impulse/convective.

In the design of high-rise building, nonlinear material and nonlinear geometrically FEA, thin floor thickness may be achieved to significantly reduce vertical loading on foundation. As for steel bridges and industrial buildings, AS4100 allows plastic deformation of a structure so that slightly yieding stress redistribution at connection joins may result in a totally different steel structural design in terms of construction cost.

Construction sequence analyses of high-rise building structures involve column concrete time-dependent stiffness/creep and core wall stiffness. A calculation based on one floor load distribution may lead to 30% difference to those from a 3-D finite element model. For an underground structure, shoring/diaphragm wall thickness sometimes may be halved by using soil-structure interaction analysis. Frame analyses for underground structures such as rigid box culverts are not considered adequate and efficient since it gives inappropriate design moment at joints. The frame analysis shall underestimate the design moment at the roof midspan, whereas using crack sections in a frame analysis may lead to wrong design actions.

Without a guess, we calculate the stress concentration for cracks of the concrete members such as Hollow slabs Double Walls; Swimming pools/water tanks; Decks and PT floors to find solutions ; See our modelling crack development during prestress Pole test.

SC offer solusions of Earth Slope Stability (we do soil-structure interaction analysis for the shotcrete design, adding anchor forces on shotcrete shall lead to impractical shotcrete design), facade structure thermal analysis, Shoring Wallfor Building Structure construction and precast solutions for coast protections using precast concrete members such asWavebreaker and crib walls

----Online Design Programs

It provides an efficient design calculation tools to design engineers. Explicit calculation formula and values are presented in the web pages and may be printed into users' design reports. To access to the online programs in full version, contact  SCSG for access code and technical supports.

 It is a advanced design program to simulate a real service condition of retaining walls. It considers loads of  vehicle wheel point, railway line, slope piling, kerb collision, handrail hanging eccentricity and etc. It also releases base pressure when one side is  uplifted by overturning.  Shear key calculation shall ultimately optimize the design to offer a cost effective solution.

 It provides an architect or a senior structural engineer to quickly confirm a  conceptual design of slender/supper highrise buildings

  It gives civil/structural engineers a efficient tool to make estimate on column/wall/pier footing bearing  capacity.

 It is a advanced design program to simulate a real service condition of eccentrically loaded footing. A nonlinear  finite element method is employed to calculate bearing and section design actions considering the release of pressures on a part of  footing uplifted eccentrically.

 It may be used for the design of drilled piers or stumps that support bridge decks, powerline towers/poles, residential houses/buildings. It may replace piles by eliminating pile caps; install in a boulder soil formation; transfer large bending moment. 

  It provides engineers a tool to quickly calculate wind forces acting on multi-storey or high-rise buildings.

Earthquake Force Calculator   It is a free run program.

    It is a free run program. The program calculates reinforcement required by the bending strength design, moment and shear capacity, steel stress, section crack width.  Compressive reinforcement, if it presented, is taken into account in the calculation
