1 Adjustment of Material Parameters to Experimental Data
Read More
This technical article describes the adjustment of material parameters to experimental data using the example of the Modified Hardening Soil Material for oedometric and triaxial tests.
The publication by Bower et al. is used as a template for this (Bower TA, Jefferson AD and Cleall PJ. A reformulated hardening soil model. Proceedings of the Institution of Civil Engineers – Engineering and Computational Mechanics 173(1): 11–29, 2020. https://doi.org/10.1680/jencm.18.00054).
2 Reinforcement of Buckets with Rough Inner Walls
Read More
The article describes the complete derivation and design of the required bucket reinforcement. Both horizontal and vertical stirrups are analyzed.
3 Shape Adaptive Loads in RFEM 6: Ponding Load Type
Read More
The article explains how the Ponding load type in RFEM 6 simulates rainwater accumulation on surfaces, accounting for surface deformations and iteratively adjusting load distributions to ensure accurate modeling of its impact on structural integrity.
4 Evaluation of Results according to WTG-Merkblatt M3
Read More
This article introduces the normalized mean squared error as a quantitative validation criterion for comparing simulated and observed data. It highlights the metric’s strengths in model calibration and its applicability to small datasets. Limitations due to sensitivity to outliers are also briefly discussed.
5 Punching Shear Design in RFEM 6 according to ACI 318-19 and CSA A23.3:19
Read More
This article outlines new enhancements introduced to punching shear design in RFEM 6, expanding on the initial feature set discussed in Part I. These updates align with the provisions of ACI 318-19 and CSA A23.3:19, offering improved precision and broader design capabilities.
