Seismic Analysis and Design Capabilities

ProtaStructure provides engineers with comprehensive tools to design and detail buildings quickly and economically to meet rigorous earthquake standards including US and EC codes of practice.

Wide Coverage of Seismic Codes

ProtaStructure supports a wide range of seismic codes including IBC, UBC, EC8, NSCP, SNI, Thai, Indian and Turkish standards.

Seismic Parameters and Response Spectra

Elastic and design response spectra are calculated automatically using code-specified parameters. Sitespecific spectra can also be introduced. Mass sources are automatically calculated including consideration of varied live load participation.

Equivalent Static Earthquake Loads

Static earthquake loads are automatically calculated and applied at story levels. Multiple diaphragms and accidental eccentricities are taken into consideration.

Response Spectrum Analysis

Mode superposition analysis can be used where static approach is not applicable. Modal results are combined with CQC. RSA base shear is automatically scaled to Equivalent Static results. Cumulative mass participation of modes is automatically calculated.

Diaphragm Modeling and Story Meshing

ProtaStructure has smart features for automatically detecting and defining intelligent rigid diaphragms. Multiple towers with discrete independent floors, discontinuous, stepping, sloping slabs and openings are all considered. Any floor can be selectively meshed and assigned as a flexible diaphragm.

Two Stage Analysis for Upper and Lower Structure

An automated two stage analysis is performed in one-go for buildings with rigid basements. Different mass sources for upper and lower structure are automatically considered.

Consider Cracked and Uncracked Sections in One Analysis Run

Cracked and uncracked section properties can be simultaneously used in the same analysis for different load cases. Code modification defaults can be automatically applied to section properties.

Vertical and Horizontal Irregularities

ProtaStructure has powerful features to assess building irregularities in accordance with earthquake code requirements. Floor Torsion, Diaphragm Discontinuity, Mass, Stiffness, Weak Storey and Non-parallel system irregularities are all checked, and any required penalties are applied.

Vertical and Horizontal Irregularities

Strong Column-Weak Beam Checks

Tedious Strong Column-Weak Beam checks are automated at every joint. Joint checks are summated bi-directionally at every floor to ensure building collapse mechanisms perform in meeting accepted code provisions.

Joint Shear Checks

Overlooking joint shear can potentially cause catastrophic failure of buildings during earthquake events. ProtaStructure automatically detects Confined or Unconfined joints and checks against brittle failure.

Joint Shear Checks

Ductile Member Design and Detailing

Columns, walls, and beams are designed to special ductility requirements. Automated confinement of beam and column critical sections, wall end zones (boundary elements), wall design envelope, capacity shear design and much more are automatically considered.

Diaphragm Integrity and Load Transfer Checks

Transfer of inertia loads between slabs and lateral load resisting members including shearwalls and collectors beams is automatically verified. For flexible diaphragms, in-plane shear, tension and compression stresses are checked to prevent diaphragm failure.

Wall Coupling Beams

Special attention is provided for coupling beams. Different cracked section properties can be defined. The wall-beams assembly is checked for coupled wall effectiveness.

Seismic Isolators

Seismic isolators can be inserted anywhere on the structure for different seismic isolation scenarios. Both upper and lower structure design can be performed in ProtaStructure using target earthquake spectra. Drift of the structure and isolator displacements are also reported as a part of the design.

ProtaStructure for Performance-Based Design and Building Assessment

Prota provides unique tools for engineers to carry out performance-based building assessment.

Nonlinear Fiber Analysis of Sections

Column, beam, and Wall sections can be modeled with fiber elements using distributed plasticity and analyzed with state-of-the-art numerical techniques to derive the Moment-Curvature relationships.

Force-deformation relationships for integration points are obtained from detailed fiber section analysis.

Nonlinear Fiber Analysis of Sections

Nonlinear Static Pushover

Single Mode Static Pushover analysis is performed using ProtaStructure – OpenSees integration. Parameters such as the number of steps and target displacements can be controlled by the user.

After the analysis, the Capacity Curve is obtained. Users can specify the monitored node for which the curve will be generated. Results can be examined at any desired step. A detailed performance assessment report is generated afterwards.

Nonlinear Static Pushover

Nonlinear Time-History Analysis

Nonlinear Time-History analysis can be performed using ProtaStructure – OpenSees integration.

User selected multiple ground motions can be applied simultaneously in X and Y directions. Ground motion application direction is rotated by 90 degrees, and analyses are repeated.

Ground motion records are automatically scaled by ProtaStructure to your design requirements using the simple scaling method between 0.2T and 1.5T.

Analysis results from multiple ground motion sets are automatically post-processed. The average values of absolute maximum responses are extracted and used to prepare detailed performance assessment reports.

Nonlinear Time-History Analysis

Design Codes

Structural engineers around the world like to employ their own local approaches to both design and detailing. At Prota we understand this which is why we offer both a broad range of leading international codes as well as provide specific customization to suit your local requirements.
