Analyses of the structural system
There is an option to move structures in a controlled process and reduce structural stresses. MAURER supports you from the planning stage right through to execution. We provide consulting services so you can achieve optimum protection for any structure while taking the specific site conditions into consideration.
Seismic analyses
At the design stage, MAURER can carry out seismic analyses in order to protect the structure against seismic events in a cost-effective manner.
Following input data and system requirements should be available:
- Location-specific response spectrums for DBE and MCE
- Seismic transients (directions and combinations must be defined); if these are not available, they can be produced by MAURER
- Total structural mass, lumped mass per storey (lumped mass model), structural damping (5% if not stipulated), natural frequencies of the first natural bending vibrations and torsion mode
- Maximum permissible inter-storey drifts and peak floor accelerations
- For base isolators: maximum target relative isolator displacement in peak earthquakes, max-imum shear in the isolator for the Design Basis Earthquake and the peak earthquake
- For inter-storey dampers: maximum target forces and displacement
Linear structural analyses (response spectrum analyses)
This simplified method only takes global parameters such as structural mass, structural damping and the location-specific response spectrum for the design basis earthquake into consideration. This method is less CPU-intensive and can be used to plan seismic isolators approximately, such as sliding isolation pendulums and lead rubber bearings by means of the response spectrum method.
Non-linear time-domain analysis (simulation)
Base isolators or inter-storey dampers are optimised on the basis of an expanded structural model with seismic transients with respect to efficiency and economy. The simulation model depicts the seismic protection system in detail with any nonlinearity and dynamic effects. Calculation of seismic transients is based on the given response spectrums. Upon request, non-linear structural damping can also be considered. Optimising the seismic protection system in this way results in significant savings in construction costs thanks to the reduction in reinforcement, steel and concrete.
Accurate determination of
- Inter-storey drifts, peak floor accelerations, base shear, forces from inter-storey dampers
- Structural motion including torsion
- Response forces that act on the structural elements and the structure
- Recentring properties of the base isolation system
- Types of isolators and/or dampers
Development of design cocnept
Calculation of several alternative solutions and concepts in the early structural design stages using the design requirements for structural elements and the resulting structural loads. Identifying the economically and technically most reasonable configuration for the structure.
