Ten Common Myths About Block And Beam Use in Constructions

Conjoined matrix that has disseminated pores that are suitable and/or disseminated particles or beads that are lightweight. The phrase of “lightweight aggregate” has a broad definition, which includes the non-polymeric and polymeric beads or particles.

Resilient Composite Systems Resilient Composite Systems are made by disseminating suitable hollow pores or by spreading the proper lightweight aggregates within the fibered and reinforced conjoined matrix so that “the strain changes in the beam height during bending” is usually “non-linear”.

By applying the above-mentioned method for making these particular hybrid systems “considerably increasing the modulus of resilience and the bearing capacity in bending” in conjunction in conjunction with “the significant decrease of the weight” and “the possibility removal of the beam fracture of primary compressive type” are all feasible. By constructing these specific functional systems that integrate the stated paradoxical advantages have been incorporated into one functional unit. 

In these units of integrated functioning in these integrated functioning units, the number and way in which the components employed in the organized system are such that the inter- (reciprocal) interactions between components ultimately result in “typically non-linear strain changes in the beam height during bending” (as the “basic functional character” of these systems ) with specific testable criteria and indexes) and functional specifications that are met by the system.

In the RCS general sense the principal strategy to increase the modulus of the system’s bending resistance involves “increasing the strain capability of the system in bending” within the elastic limit.

The main strategy to implement the strategy is “creating the suitable hollow pores and/or using the appropriate lightweight aggregates, all disseminated throughout the methodically reinforced conjoined matrix” for the chance of generating the most effective internal deformities within your matrix throughout the bent process that could result in an optimal distribution of stresses and strains across the entire system and the increased strain capacity of the beam during flexure. In contrast simply creating hollow pores or using lightweight aggregates within the matrix by itself will not result in the goals mentioned however, it also causes fragility of the matrix. its fragility. Construction design is very important and a number of experienced autocade experts emphasis use of block and beam  for prolonged durability of the buildings.

Also, it is essential that the matrix needs to be protected and strengthened. This is basically improving and strengthening of the matrix is accomplished by paying consideration at “the internal consistency of the matrix” and by “employing the expedient reinforcements in two complementary levels”: 1.) using fibers to ensure a better distribution of strains and stresses in the matrix, and also to improve the endurance of the matrix and the modulus of resilience under the bending and tension; 2.) using an elastic mesh, or lattice for better distribute the strains and stresses within the system, and to improve the system’s endurance and strength modulus during tension and bent.

In these systems there are hollow pores or the light aggregates that are dispersed across the matrix (which is improved by the creation of “an integrated, reticular structure”) gives the potential for the occurrence of the efficient internal deformations in the matrix during the bending process. In the end, this will result in the lesser accumulation of internal stresses in certain areas of the matrix when it is bent which will allow for greater absorption and management of the strains, and allowing for greater strain capacity of the beam particularly in the limit of elastic.

The occurrence of the mentioned internal deformities of the methodically reinforced matrix in the bending course is also that there are deformities of the hollow pores or lightweight aggregates dispersed throughout the conjoined matrix in two distinct types. In fact, we can observe internal deformities of the fibered light matrix during the entire bending process, in two different shapes, which leads to two main forms: A)

The increase in layer’s thickness (height) of compressing sections (particularly on the higher portions of the beam) and the conversion of internal compressive stresses into internal tensile stress (on the axis parallel to the compression tensions internal to the beam) in the compressing layers (B) The diminution of the thickness (height) of the in-tension layers (particularly in the lower portions of the beam) and the conversion of certain internal tensile strains to internal compressive tensions (on the axis parallel to the tensions in the internal tensile layers) inside the layer of tension.

In the sections that are under-bending of “Resilient” Composite System, the “Resilient Composite Systems”, the deformations that occur within these “conjoined layers perpendicular to the applied load direction” during the bending course is such that “the initially plane sections perpendicular to the beam axis” tend to change between “the plane status” to “the curve status” during the course of bending.

This is why the geometry of the flexure theory within Solid Mechanics (“linearly” being of the strain variations in the beam’s height during the bending) and the trigonometric equations and equations are mostly ignored by these systems.

Through the development of the internal deformations in the mat during the stretching process The stresses are more evenly distributed and absorbent by the matrix, and the rates of increasing internal stresses within the matrix (which could cause cracks and plasticity of the matrix) are reduced.

In fact, in this type of system, aforementioned internal deformities of the beam when it is bent create that so-called Neutral Axis in the beam shift downwards. (This trend to shift downwards is in contrast to the tendencies to move upwards of the neutral axis in beams constructed of typical steel reinforced concrete, which tends to shift upwards in the course of bending.) Therefore, the greater strength of the beam is offered.

In actual fact, because of the way in which the mentioned inner changes (in two types) in the conjoined and reinforced lightweight matrix during the bending course, we are experiencing “typically non-linear strain changes in the beam height during bending” which is why this non-linearity is regarded as the primary functional criteria (with its indexes) of Resilient composite systems.

The one that is mentioned as “Elastic Composite, Reinforced Lightweight Concrete (E.C.R.L.C.)” is a form of “Resilient Composite Systems (R.C.S .)”. This type of RSC (with the previously mentioned general structural properties and the specific functional requirements) which cement materials comprise those known as “C-S-H (Calcium Silicate hydrate) crystals” are known as ECRLC. For instance, the mix that comprises “Portland cement and water”, “Portland cement and water and Pozzolanic materials”, and “lime and Pozzolanic materials” all belong to the cement elements that make up C-S-H crystals.[]

With regard to the particular pattern of strain that changes during the bending process in the specific Resilient Composite System, also known as ECRLC This system, as an integrated unit that includes the reticular arrangement as well as texture, is more suited to ability to withstand strain (especially in the limit of elastic) as well as capacity for energy absorption and bearing capacity when bent bending, compared to conventional reinforcement concrete beams.

It is evident that using hollow pores or lightweight aggregates (such as Polystyrene beads) in the matrix can lead to a reduction in density. In this manner we can also gain access to what is known as thermal insulation, which is a lightweight material in accordance with the circumstances. Then, you can add

By using this type of structure, there is the possibility of resolving some of the major issues that arise in the lightweight concretes, particularly the strategic deadlock that is brittle and insecurely breaking the pattern found in a lot of common reinforced lightweight concrete structures is available by reaching the higher capacity of bearing in the bent elements (even with small dimensions and weights) is at hand as well as accessing an easy and feasible opportunity to “the qualitative development of the capabilities for using the lightweight concretes” is possible.

In this case, it is worth of noting that, if required or “according to the case” in addition to using other methods and other elements (such as supplementary reinforcements such as connecting strips and foam pieces, as well as strengthening in various levels, etc.) in line to these systems can be considered. In general, these additional elements aren’t required for a system to be considered the one that is known as the Resilient Composite System (Resilient Compound System).

In light of the subject matter and specifics discussed in considering the specifics and subjects for RCS as well as the ECRLC (as an easy and useful technology) These systems could be utilized effectively as “in-bending” and in-torsion elements and for constructing components that are able to shield by absorbing impacts and vibrations, shocks, as well as dynamic load (in the bending).

In addition, taking into account of the properties like lightweight as well as durability, insulation, work-ability and the possibility of high-formability of certain components utilized for these types of systems (such as a particular type of concrete lightweight with the capability to endure high strains) and the possibility of using additional elements and techniques (according to the circumstances) These systems as well as certain of the components used like the particular lightweight concrete, could be used in a variety of ways.

They can be used in the building of slabs or floors, roofs, floors, decks bridges, shields and parts to protect against blasts and explosions, roadside walls, guards, and partitions, various types of slabs, Tracks and the Traverses (under railways) as well as various other structures and structures, such as multi-floor parking garages and buildings and towers as well as marine constructions and floating structures, interspersing structures as well as lightweight façade pieces cabinets, wood and ducts. and more.

The mentioned characteristics from the RCS & ECRLC have the important role to play in the construction of towers and high-rise buildings and, in particular, in construction in those “seismic areas”. Lightness, higher modulus for resilience, the capacities for energy absorption as well as conserving during bends, the secured break pattern and the right behavior against high impact as well as vibrations appropriate strength, and not benefiting from the heavy weight and separate materials that exhibit discordant behavior are just some of the features that are crucial in this regard.
