Armorflex blocks have specific tested hydraulic capacities and are laced longitudinally with revetment cables to provide ease of handling and rapid installation.
Structural paving mats.
Structurepoint formerly the pca engineering software group offers concrete design software programs updated to aci 318 14 for concrete buildings concrete structures and concrete tanks.
The slab is idealized as a mesh of rectangular plate finite elements with four nodes at the corners and three degrees of freedom dz rx and ry per node.
The structural design of mat foundations can be carried out by two conventional methods.
Reinforced concrete structural software includes programs for column design pcacolumn beam design pcabeam slab design pcaslab wall design pcawall mat design pcamats foundation design tank.
Types of mat raft foundation.
Flat plates beams with a slab underneath like waffle slab construction and beams with a slab on top.
The principles of reinforced concrete design were used to design the mat with three types of mats recognized.
Armorflex is a flexible interlocking matrix of cellular concrete blocks of uniform size shape and weight used for hard armor erosion control.
This type of foundation is suitable when the soil is not compressible.
Flat plate raft is used in the small and lightweight load structure.
Keystone began construction of a 23 story high rise in west houston with a successful placement of the mat foundation.
7 600 cubic yards of concrete were placed for the foundation in a continuous operation over a 10 hour period starting at 10 00pm and finishing around 8 00am the next morning.
Today engineered bar mats are a low carbon high strength steel for structural concrete applications.
There are following types of mat foundation flat plate raft.
Finite difference and finite element methods can also be used but this section covers only the basic concepts of the first design method.
Plate thickened under columns.
Spmats program uses the finite element method for the structural modeling and analysis of reinforced concrete slab systems or mat foundations subject to static loading conditions.
The base floor may also be comprised of a mud or structural foundation slab complete with waterproofing and wearing slab with the overall system designed to carry structural hydrostatic pressure loads and maintain a controlled environment.
Two way slab and beam.
Becasue they can be adapted to perform well in a wide range of climate zones and difficult soil conditions.
