BOSTD Geogrid MSEW design software is used to design these structures that are built of BOSTD uniaxial geogrid, fill materials a facing panel system and drainage. Fill materials can be from local sources eliminating high transport costs, Construction techniques often only require labour and simple machinery, The overall project cost is normally significantly less than traditional reinforced concrete structures. The structure is flexible and can better adapt to foundation deformation due differential settlement and is proven to have good anti-seismic performance. There are many options for facing design of the wall including pre-cast panels and modular blocks with a variety of shapes, surface designs and colours to harmonize with the surrounding environment, adjacent buildings, bridges and other construction, and can form unique, attractive retaining walls.

Apr 29, 2021 MSEW (MSEW(3.0).exe) latest version 3.09.1000, MSEW is an interactive program for the design and analysis of mechanically stabilized earth walls. It follows the design guidelines of AASHTO98/Demo 82, AASHTO02/FHWA-NHI-00-043, AASHTO 2007-2010, or NCMA97/98. Based on the results of the comprehensive evaluation of this software as well as the design and stability analysis undertaken within this Study, it is concluded that the MSEW 3.0 requires. Download MSEW 2 free. Nowadays computer has become a universal tool and can be used in any context.

MSEW(3.0) is an interactive program for the design and analysis of mechanically stabilized earth walls. It follows the design guidelines of AASHTO98/Demo 82, AASHTO02/FHWA-NHI-00-043, AASHTO 2007-2010, or NCMA97/98. Note that AASHTO98/02 is based on allowable stress design (ASD) whereas AASHTO 2007-2010 is based on load resistance factor design (LRFD). NCMA is limited to geosynthetic reinforced segmental retaining walls (SRW). Although the program generally follows the guidelines of established design procedures, the user can explore design options and concepts beyond the formal guidelines; the user can override all default values. Such exploration is useful for the development of new systems as well as the occasional need to conduct forensic study.

MSEW(3.0) allows for global stability analysis using Bishop method with circular arc. For more in-depth and efficient global analysis, MSEW(3.0) can export data files for analysis using ReSSA(2.0). The exported data includes elements such as connection strength thus facilitating a more comprehensive stability analysis for which ReSSA is ideal. Furthermore, by a click of a button, virtually all tables in MSEW(3.0) can be exported to Excel or be printed. Files generated using MSEW(2.0) can be read using MSEW(3.0). The same applied to database files.

ADAMA Engineering developed the copyrighted program MSEW Version 1.0 for the US Federal Highway Administration (FHWA) [Link to FHWA website announcing the release of version 1.0]. Version 1.0 has been designated exclusively for use by US State Highway Agencies and by US Federal agencies. ADAMA Engineering offers version 3.0 to the public. This version includes many enhancements such as calculations of quantities, more versatile surcharge loads, use of Coulomb lateral earth pressures for both internal and external stability, user's generated databases, improved presentation of slope stability results, graphic files compatible with AutoCAD®, design methods based on NCMA or LRFD, and more.

The Help in MSEW(3.0) software includes relevant sections of Demonstration Project 82 ( Ntlite keygen. Publication No. FHWA-SA-96-071) as well as a revised version of Demo82 (FHWA NHI-00-043). These manuals serve as the basis for AASHTO 98/02 (ASD). The details of AASHTO LRFD design are provided in the Bridge Section of AASHTO guidelines; it is recommended that the user purchase a copy of these guidelines from AASHTO.
MSEW(3.0) also includes an option to use the NCMA design method. This option is limited to block (segmental) walls having simple geometry and using geosynthetic reinforcement (same as the instructions in the NCMA guidelines). The NCMA design procedure, as implemented in MSEW(3.0), is detailed in:
