Structural Paving Mats

Flat plates beams with a slab underneath like waffle slab construction and beams with a slab on top.

Structural paving mats.

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. 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. 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. Plate thickened under columns.

Flat plate raft is used in the small and lightweight load structure. There are following types of mat foundation flat plate raft. Two way slab and beam. Armorflex is a flexible interlocking matrix of cellular concrete blocks of uniform size shape and weight used for hard armor erosion control.

Types of mat raft foundation. Finite difference and finite element methods can also be used but this section covers only the basic concepts of the first design method. The structural design of mat foundations can be carried out by two conventional methods. The mats are resistance welded using computer controlled automated welders that produce custom designed flat sheets that can be bent rolled and even galvanized or epoxy coated.

Keystone began construction of a 23 story high rise in west houston with a successful placement of the mat foundation. Becasue they can be adapted to perform well in a wide range of climate zones and difficult soil conditions. Structural slabs slab on grade foundations are one of the most common foundations in the u s. The conventional rigid methodand the approximate flexible method.

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. 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. The principles of reinforced concrete design were used to design the mat with three types of mats recognized. 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.
