SimTunnel Pro vs Plinth Usage & Stats

SimTunnel Pro is designed to perform a quick tunnel analysis on your phone device. SimTunnel Pro is very simple and easy to use. SimTunnel Pro uses "rock-support interaction" or "convergence-confinement" method to estimate the deformation of circular tunnels in weak rock, and visualizing the tunnel interaction with various support systems. SimTunnel Pro has the following features: - SimTunnel Pro determines Factor of Safety (FOS) as the ratio of maximum support pressure to the support pressure required for equilibrium. - The Tunnel and Rock Parameters dialog allows you to define the tunnel and rock properties for model. - The Strength Properties which are required will depend on the strength criteria you have selected in Setting Page. - Both Mohr-Coulomb and Hoek-Brown strength criteria are available. - The parameter calculator dialogs are available to help you to calculate some of the parameters (i.e. GSI, mi, D, UCS, insitu stress and etc). - The support parameters dialog allows you to easily add support and define the support properties for the model. - Three different support types can be added to the model: Rockbolts, Steelsets and Shotcrete - The ground reaction curve (GRC) is always displayed in the output page. - The brief summary of analysis results and input data will be displayed in the Output Page. - The report button, allows you to save the current model’s input and output information into PDF file. The generated report file can be sent out via email.

Plinth

Plinth is the app to compute and verify shallow foundations using the allowable-stress method. Features: - Bearing capacity of shallow foundations against general shear failure (Hansen 1970, drained and undrained conditions) and punching (Vesic 1975, drained conditions) - Can be used with mono and multi-layer soils - Can be used with eccentric and inclined loads with also verifying horizontal friction - Can be used with inclined foundation and ground - Compute the weight of the plinth and the water pressure if present - Can be used with base slab and continuous beam - You can choose between metric or imperial system - Theory and standard equations for all formulas used and typical geotechnical parameters available - Detailed step description and e-mail sending of all computations and results Plinth is the must-have app for every pro and student in structural world. With few steps you can, once known some geotechnical parameters of the soil, verify with detail the security factor for shallow foundations and understand the collapse mechanisms that may happen. Theory and standard equations describe the process and relations used by the app giving you all the basic information you need.
