Fire resistive construction-firewalls

By -

The fire-resistive construction method will involve the designing and construction of fire resisting elements such as firewalls, fire barriers, fire partitions, smoke barriers, and smoke partition. The purpose of these components is to restrict the spread of fires between building units. Firewalls should be continuous from the foundation to the building roof, and it should have sufficient stability to resist the collapsing if the construction on either side collapse. Firewalls used to separate a structure into multiple units, which reduce the severity and consequences of fires by limiting the fire in one area and prevent the spreading of the fires to other structures area. Fire barriers and partitions are interior walls used to sub-divide the portion of a building that concealed by firewalls into smaller areas. Fire barriers and walls will be supported by the adjacent structure. They will prevent the heat flows within the area concealed by firewalls, which gives the residents sufficient time to evacuate. The purpose of using smoke barriers is to restrict the smoke movement and fires. Similarly, smoke partitions used to limit the movements of smoke but not necessarily to prevent the spread of fire.     
Figure 1
Fire-resisting elements will significantly reduce the impact of fire on a building. Fire-resistive construction of a structure will restrict the fire, which reduces the property damage. Moreover, it is providing occupants with sufficient time to leave the structure by containing the fire in one area and not allowing it to spread. Fire-resisting elements should have a specific resistance rating, and it should be tested to verify this property. Fire-resistance rating is the duration at which a building element, component, or assembly maintains the ability to confine a fire, continues to perform a given structural function, or both. The rating will be different according to structure importance. It can range from 2 hours for storage facilities and factories to 4 hours for high hazard facilities. IBC code (international building specification) provides a table showing the required fire resistance for different groups of structures. 

Firewalls usually are thicker than typical walls. Also, it is designed to remain stable even if the adjacent structures collapse. the designer of firewalls shall ensure the following points:
  • stability
  • Other forces affecting the wall include the collapse of an adjacent roof structure or adjoining buildings.
  • Effects of the thermal expansion of the adjacent structural steel or the wall itself.
  • It should be designed as a non-loadbearing member. It should carry its own weight only. however, the structural framing within a tied firewall can be loadbearing.

Bar Bending schedule (BBS)

By -
Image
 The bar  bending schedule is a table that contains the details of reinforcement for a specific structural member such as footing, column, slab, and others. The bar bending schedule will contain the bars' dimensions to be used, the shape of the bars, the size of bars, bar mark, number of bars, and the weight of bars. BBS will be used to determine the weight of reinforcement required for a specific structural member.  there are various advantages of bar bending schedule such as: estimating the quantity of reinforcement for each structural member. So we can estimate the amount of reinforcement required for a construction project.  BBS will help in reducing the losses of steel by procuring the precise quantity of different rebar diameter.  BBS will reduce the wastage of reinforcement by providing the engineers with the exact dimension and shape of rebars. Knowing the exact dimension and shape will reduce the time of cutting and bending rebars.  BBS will reduce the effort at the time o

Binding wire for steel reinforcement

By -
Image
  Binding wires are used to tie steel bars together. These wires are playing a significant role in maintaining the reinforcement stability and rigidity. Wires are used to tie the steel bars at intersections points. By tying the steel bars together, we ensure that the steel bars will not move from their locations during construction or during the time of concreting. In slabs, binding wires are used to tie longitudinal and transverse bars together. In columns, it is used to tie vertical bars with stirrups.   Figure 1 There are various types of binding wires such as  Black annealed baling wire, Stainless Steel Binding Wire, and PVC coated binding wires.  Black annealed baling wire used to tie black steel. The popular size for black wire ranges from 16 to 22 gauges. Stainless steel binding wires are used to bind stainless steel reinforcement. Stainless steel reinforcement is used in a harsh environment where the black steel gets rusted quickly. Therefore, stainless steel reinforcement is u

Repairing of concrete bulging

By -
Image
Improper designing and installation of formwork for a concrete member can result in concrete Bulging. During the placing and compacting of concrete, forms may deflect largely in the weak areas. The deflection of forms will cause concrete to expand at this location, and this known as concrete Bulging. Concrete Bulging will spoil the appearance of a concrete member. Therefore we should always ensure that the forms are appropriately installed, and it is sufficiently supported to resist the concrete during placing and compacting. Bulging should be repaired in case we couldn't avoid it. The solution of concrete Bulging, offset, or surface irregularities are surface grinding. However, excessive surface grinding can weaken the concrete.  Figure 1 If the bulging or surface irregularities are small, grinding of concrete surface will be sufficient to remove surface irregularities. If the Bulging of concrete is significant, then the concrete should be chipped, and the surface

Bridge Diaphragm

By -
Image
The main function of diaphragms is to provide a stiffening effect to deck slab in case bridge webs are not situated directly on top of bearings. Therefore, diaphragms may not be necessary in case bridge bearings are placed directly under the webs because loads in bridge decks can be directly transferred to the bearings.On the other hand, diaphragms also help to improve the load-sharing characteristics of bridges. Diaphragms also contribute to the provision of torsional restraint to the bridge deck. Diaphragm will be used also to resist stresses that occurs during the post-tensioning process. Post-tensioning hardware are casted inside the diaphragm. Figure 1 construction management: concrete construction bridge construction:How to become a bridge engineer Types of diaphragm: Diaphragm at the span end: this type of diaphragms will be located between two bridge spans or at the bridge abutments. Expansion joints will be used to connect bridge spans. This

shear key

By -
Image
The purpose of the shear key is to improve the bonding between concrete surfaces. The shear key is usually made at the construction joint location to enhance the adhesion between the old and new casted concrete. Construction joint is considered a weak point because the concrete is not casted at one time, in large structures where the concrete can not be casted for some members at one time, such as a slab. We usually divide the slab and cast it at many stages. The large quantities of concrete will make it impossible to cast the slab at one time. Therefore, the casting will be done in several stages. The location of the construction joint should be selected carefully. Construction joint shall be made at the location of minimum shear and moment.  The bonding between old and new concrete can be improved by roughening the old concrete and forming a shear key on the concrete surface while the concrete is still plastic. The shear key can be formed by pressing timber into the concrete surface

Concrete is a widely used material. Reinforced concrete structures can be found everywhere. The main reason behind the popularity of reinforced concrete structure is the high strength and the long life span of these structures. Concrete and steel are combined to produce reinforced concrete. Concrete is good at compression while steel good at tension. Concrete and steel form a perfect combination to resist loads imposed on the structure. Concrete is a composite material composed of cement, coarse aggregate, fine aggregate, and water. Admixtures can be used to enhance concrete properties. A concrete mix consists of almost 65% aggregates. Aggregates are classified into fine and coarse aggregates. Since the aggregates form the majority of a concrete mix. The quality of aggregates can greatly affect the strength and durability of concrete. Aggregates can be natural or crushed aggregates. Used aggregates should be strong, hard, and should not contain a large amount of organic matter or harmf
