The combined finite discrete element method is a relatively new computational tool aimed at problems involving static and / or dynamic behaviour of systems involving a large number of solid deformable bodies. Such problems include fragmentation using explosives (e.g rock blasting), impacts, demolition (collapsing buildings), blast loads, digging and loading processes, and powder technology.
The combined finite-discrete element method - a natural extension of both discrete and finite element methods - allows researchers to model problems involving the deformability of either one solid body, a large number of bodies, or a solid body which fragments (e.g. in rock blasting applications a more or less intact rock mass is transformed into a pile of solid rock fragments of different sizes, which interact with each other). The topic is gaining in importance, and is at the forefront of some of the current efforts in computational modeling of the failure of solids.

Engineers have to predict the behaviour of various materials when they are loaded by mechanical forces. Geotechnical engineers are no different to other engineers in this respect : they have to predict the behaviour of soil whereas other engineers deal with steel, concrete, wood, plastics or fluids. In describing the behaviour of materials, engineers use a number of conceptual 'models' which are simplifications of real behaviour. Examples of these models include linear elastic solids, perfectly plastic solids and viscous fluids. If we compare the behaviour of each engineering material with the appropriate conceptual model, then we will always find some differences in detail. However, the important point is that the conceptual model is often sufficiently accurate for the purposes of engineering analysis and design. Associated with each of the examples listed above there is a collection of standard solutions to commonly occurring problems to which the engineer can refer (i.e. the theories of elasticity, plasticity and fluid mechanics) .
Soil behaviour conforms less to the models of material behaviour that we have mentioned so far than do most engineering materials. This is because soil is a two-phase material consisting of solid particles and wa ter. Its response to being loaded is inheren tly more complex than the response of steel or concrete, for example. Another complicating factor arises because the distribution of soil properties in a typical deposit (such as stiffness and strength) is non-uniform. In particular, soil properties always vary with the depth below the ground surface and this will usually have to be taken into account in engineering design.

Finite Element Modeling of Reinforced Concrete Structures Strengthened with FRP Laminates
Author: Damian Kachlakev, Thomas Miller | Size: 2.78 MB | Format:PDF | Publisher: Oregon State University | Year: 2001 | pages: 113
A large number of reinforced concrete bridges in the U.S. are structurally deficient by today’s standards. The main contributing factors are changes in their use, an increase in load requirements, or corrosion deterioration due to exposure to an aggressive environment. In order to preserve those bridges, rehabilitation is often considered essential to maintain their capability and to increase public safety (Seible, et al. 1995; Kachlakev 1998).
In the last decade, fiber reinforced polymer (FRP) composites have been used for strengthening structural members of reinforced concrete bridges. Many researchers have found that FRP composite strengthening is an efficient, reliable, and cost-effective means of rehabilitation (Marshall and Busel 1996; Steiner 1996; Tedesco, et al. 1996; Kachlakev 1998). Currently in the U.S., the American Concrete Institute Committee 440 is working to establish design recommendations for FRP application to reinforced concrete (ACI 440 2000).

STAAD Foundation Advanced V8i (06.00.00.51) - TRIAL VERSION
info: STAAD Foundation Advanced V8i (06.00.00.51)
STAAD Foundation Advanced is a comprehensive foundation design program which offers the ability to model complex or simple footings, including those specific to Plant facilities such as octagonal footings supporting vertical vessels, strap beam foundations supporting horizontal vessels, ring foundations supporting tank structures, and drilled or driven pier foundations.
Common foundations such as isolated footings, combined footings, strip footings, pile caps, and mat foundations can also be designed for larger structures or using parametric wizards. It provides a streamlined workflow through its integration with STAAD.Pro and can also be used as a stand-alone program.
It is very important to note that this is not an automatic update from old STAAD.foundation software. The license for STAAD Foundation Advanced is different than the license used in STAAD.foundation. So, to run this program, existing users of STAAD.foundation need to contact their respective Bentley sales representative to get a new license.
