ProtaSteel allows structural engineers and detailers to perform automated steel connection design and produce high-quality steel detail drawings in minutes. You can take models designed in ProtaStructure directly into ProtaSteel and save hours with the automated design of a comprehensive range of bolted and welded steel connections of your choice. Also, you can visualize and coordinate your […]
Response Spectrum Analysis calculates and combines the pseudo maximum responses of natural vibration modes against a given design spectrum by assuming each mode as an independent single degree of freedom system. During the combination of modal result vectors, the sign of the displacements and internal forces are lost and hence equilibrium condition is not satisfied […]
An important improvement since ProtaStructure 2025 onwards is the use of bending moment and shear force design envelopes in shearwalls. To ensure that the ductile shearwalls, with Hw/Lw ≥ 2, remain elastic above the base hinge considering the uncertainties in the structure dynamic behavior, the design bending moments and shear forces obtained from analysis are magnified. […]
This document highlights general and project-based guidelines to model base isolators for seismically isolated buildings. Moreover, design requirements and reporting of the results are covered in this design guide. Some tips and recommendations for the selected seismic codes are also given. We present this design guide to your attention with the hope that it will […]
Base plates play a critical role in steel structures by providing a stable and reliable interface between steel columns and their supporting foundations. These structural members ensure the safe transfer of loads from the steel column to the concrete foundation, allowing for even distribution of forces while preventing local failure or excessive stress concentrations. In […]
ProtaStructure determines the seismic separation condition according to ASCE 7-16 Clause 12.12.3. In this document, calculation details about seismic separation conditions are explained. We present this design guide to your attention with the hope that it will be useful. You can find the guide as a PDF file in the attachments.
Space trusses are three-dimensional counterparts of planar trusses. They consist of straight members connected at their ends. These members can be made of steel, aluminum, or other materials. The joints in space trusses are typically ball-and-socket joints, allowing rotational freedom. This flexibility enables the truss to accommodate various load conditions. ProtaStructure 2025& later versions, comes […]
ProtaStructure determines the seismic joint condition according to EC8 Chapter 4.4.2.7. In this document, calculation details about seismic joint condition are explained. We present this design guide to your attention with the hope that it will be useful. You can find the guide as a PDF file in the attachments.
This design guide discusses the Beam Design to British Standard Design Code BS 8110‐1:1997. Users who wish to understand the analysis and design calculation for storey beams, are recommended to read this document.
This design guide discusses the Column Design to British Standard Design Code BS 8110‐1:1997. Users who wish to understand the analysis and design calculation for braced and unbraced columns, and circular columns are recommended to read this document.
