◆ Crack Analysis Techniques for Concrete Structures
NK Computing Codes: discrete approach for multiple-crack problems; smeared crack approach for 2-D and 3-D problems; design-aided package for sewage systems-SPRANA
Evaluation of the Load-carrying Capacity of Aging and Renovated Sewer Structures
STEP1：Evaluation of the residual load carrying capacity of existing sewers
⇒ Safety analysis of existing sewers based on the load-carrying capacities.
STEP2：Renovation design
⇒ for an economical and safe renovation design
SPRANA-Design-Aided Package for Renovation Design of Sewage Systems
SPRANA is developed with the objective of aiding practicing engineers for high-quality design with ease.
Safety Analysis of Concrete Structures (Tunnel Linings, Concrete Dams, etc) with Severe Cracking
Safety analysis of tunnels, concrete dams, etc., requires accurate crack analysis of multiple cracks, based on the extended fictitious crack model.
◆ Structural Safety Verification on Seismic Resistance Using Damage Evaluation
and Nonlinear Dynamic Response Analysis
Seismic safety verification of concrete dams, underground structures, etc., based on dynamic response analysis
