Spectral Analysis
Earthquake Spectral Analysis is much more superior to the Equivalent Static method, and provide more realistic results. It considers the earthquake as a dynamic load and the earthquake forces are based on the dynamic properties of structure, and its interaction with the earthquake load. Generally, the Spectral Method will provide lower earthquake forces, in comparison with the simplified Equivalent Static Method, and it should be used as a preferred method for earthquake design.
The earthquake action is provided by a spectral curve. R/C BUILDING software has a few built-in typical spectral curves from past seismic events, and complete library of the curves provided in AS 1170.4-2007, Section 7

The Spectral solver in R/C BUILDING software provide some unique features, such as automatic floor mass center offset (0.1b), and wall group reactions, suitable for lift cores design. These features make R/C BUILDING software the most suitable design tool for earthquake design.

We combined our 4-step spectral analysis procedure in one step. Now everybody can benefit from the spectral analysis with one click.
4-step 3D Complete Spectral Analysis Procedure
With all so many structural building analysis software out there, R/C Building stands out as the one that has the leanest tool sets to master, yet provides the engineers with the powerful and sufficient tools to complete their design job.
Using R/C Building 2009, user can construct a model in a matter of a day or two, saving the valuable time to review the structure and modifiy the design based on the comprehensive results the software produces.
"For reinforced concrete buildings, R/C BUILDING software wins hands down as a lateral analysis and design tool, and we will continue to use it for our lateral analysis checks."
