Complete building design software in one powerful package
GSA Building is the ultimate building design software, steel structure design software and steel structure analysis program. It gives engineers all the tools they need to design and analyse even the most complex buildings.
The complete solution for building design and analysis
With this intuitive software, engineers can design structural models with skeletal frames and two-dimensional finite elements. GSA Building also combines steel and concrete design, footfall and soil-structure interaction analysis in the same tool. For seamless working, GSA Building is fully integrated with Revit Structure and works to a range of international codes.
Why design concrete slab or wall reinforcement by hand? GSA Building saves time and money by designing reinforcement directly from the analysis results. And if steel beams and columns had to be chopped up into elements for frame analysis, the software puts them back together and designs them automatically. It even analyses how the structure interacts with the ground or predicts the footfall vibration on irregular floors or staircases, whether they’re concrete, steel, or composite.
GSA Building also integrates with BIM applications such as Revit for design coordination across the team.
Designed by engineers for engineers, GSA Building has met the demands of projects like 32 St Mary Axe in London (The Gherkin), the National Assembly for Wales in Cardiff and the CCTV building in Beijing.
Footfall analysis / human induced vibration
As designs become more efficient, the resulting structures get lighter and more responsive to human induced vibrations. This means that footfall induced vibration is becoming an important serviceability design requirement for office and residential buildings, foot bridges and staircases: it is an essential requirement for demanding situations such as hospitals and laboratories.
GSA Building enables you to find the footfall response over the whole structure, with full contour plots and detailed graphs showing exactly where the satisfactory and problem areas are. You can thus explore cost-effective design solutions and advise you client on how their structure will respond to human induced vibration.
Find how your structure interacts with the ground for optimum foundation design
GSA Building is perfect for busy foundation designers as it enables you to analyse how your structure interacts with the ground for optimum design. This easy-to-use software combines non-linear structural and geotechnical models to calculate accurate settlements, soil pressures, bending moments and other structural stresses in a fraction of the time.
GSA Building adds the acclaimed Pdisp soil pressure displacement engine to GSA Building’s finite element analysis. The structure then interacts with the ground via piles, rafts or pads so they both work together to carry the load, whatever the structure, whatever the soil. GSA Building also integrates with Pdisp, importing soil models and exports results for further geotechnical investigation.
Check your steel structure to a number of international design codes, whether American, British, European, Australian, Indian or Hong Kong.
Concrete slab and wall design
Calculate the reinforcement requirements for concrete slabs and walls to international codes from America, Britain, Europe, Australia and Hong Kong. GSA Building takes into account not just the bending moments, but also all torsion and in-plane forces to ensure that your structure is designed for all the forces it experiences.
Output the results in both scaled contour plots for rationalisation and design calculations for both sensible construction and design confidence.
Analyse structures with large (and indeed very large) deflections, plastic yielding of materials, snap-through, sway effects, and more. GSA Building uses the dynamic relaxation method to enable you to analyse structures that other programs will not touch.
GSA Building enables you to calculate the buckling load factors on a range of structures, from complex frames to shell structures and lateral torsional buckling of plate girders. It also includes non-linear buckling effects so you can plot the deflections of columns and struts against load to accurately assess safety factors.
Dynamic analysis and response
GSA Building includes both modal analysis for calculation of the natural dynamic frequencies of your structure and Ritz analysis specially designed for seismic response calculations. You can choose to include axial load effects to change stiffnesses in both these methods.
Following on from the modal or Ritz analysis, GSA Building enables you to calculate the structural response using a number of dynamic post processors, including seismic response to multiple international codes, linear time history, harmonic loads for vibrating machinery, and more.
With staged analysis you can assess the model at any stage in construction, remove elements, and change sections and restraints, all coordinated in a single model.
