Everything You Need to Know About Brick Work

Brick dividers are likely the most well-known structure components in development of a house in India. These dividers structure fundamental units for making rooms that make up a house. The dividers other than being space dividers are additionally primary components that move the heap of the rooftop to the ground.

Brick dividers are developed on strip spread or pontoon establishments that help the dividers. The dividers are built utilizing bricks and mortar. These can likewise be developed with different primary characteristics and thicknesses.

Brick dividers are built by getting bricks together with concrete mortar in game plans called English Bond, Flemish Bond or Rat Trap Bond. These bonds give diverse outer appearances to the divider. All development frameworks of brick dividers are such concocted that vertical cross joints in any layers are amazed. The bricks hence reinforce a strong mass that doesn’t part when the divider is stacked with live loads and dead loads.

Basics About RCC Slabs in Construction

RCC stands for reinforced cement concrete slabs. It is the most important element in the construction industry to make a building. RCC slab is a structural component. The RCC slabs are supported on the columns and beams. RCC Slabs whose thickness ranges from 10 to 50 centimeters are most often used for the construction of floors and ceilings.

Thickness of RCC

The minimum thickness of RCC slabs is 5 inches. According to the AMERICAN CONCRETE INSTITUTE, the minimum thickness of the RCC slab should be 5 inches. According to Indian Standard, the minimum thickness of the RCC slab is restricted to 4 times the nominal size of aggregate. The minimum thickness should not be less than 4.75 inches.

Types of Slabs

Corrugated Slab – this is the type of slab where the concrete is poured into a corrugated steel tray. This type of RCC slab increases the strength and prevents the slabs from bending under their own weight. It runs across from side to side.

A Ribbed Slab – this type of slab provides extra strength in one direction.

A Waffle Slab – this type of slab gives added strength in both directions.

One-way Slab – this type of slab has structural strength in the shortest direction.

Two-way Slab – it has structural strength in two directions.

Comparative Analysis of Slab to Beam Load Transfer

Load transfer mechanism in reinforced cement concrete (RCC) structures are a truly intriguing matter. The loads of a floor fall totally on the floor slab. They are transferred to the beams, then to the columns, and finally to foundation. Today, we will do a comparative analysis of slab to beam load transfer.

The forces acting on a slab are expressed as slab pressure loads, which are told in terms of kN/m2. However, when these loads are transferred to the beams supporting the slab, they morph into what we call line loads on beams, given in kN/m. This transfer has to be uniform on all sides (unless you have designed it specially for skewed loads) or else the flooring may crack, or worse.

Reynolds and Steedman (2005) present some very useful formulas to represent uniformly distributed slab loads transferred to beams. These formulae are great for analyzing the load transfer system from a two-way or one-way slab to its supporting beam.

Types of Loads that Can Act in a Structure

If you’re a construction or civil engineer, probably 80% of your day goes by juggling loads acting on a member and strengths of the member. You will need to know all the types of loads that can act in a structure for designing it proper and strong. So, today we will discuss the types of loads.

The loads acting on a building can be divided into 3 main categories depending on the direction of their application – vertical, horizontal, and longitudinal. Among these, vertical loads are the most common since this is the way gravity acts.

There are many kinds of things causing vertical – or, gravitational loads, like the dead weight of a member, the live weight of things resting on that member, and the load of something impacting from above.

The most common types of loads acting in a structure are as follows:

1. Dead load
2. Imposed load
3. Wind load
4. Snow loads
5. Seismic forces
6. Shrinkage, creep, and heat effects
7. Other types of loads

Let’s run through each of these types of structural loads one by one now.

Dead Load

All the weight of the building itself is considered as the dead load of the structure. When considering a member, the dead load of the member is its own weight. The dead load acting on it would be the weight of all the permanent construction resting on the member.

Techniques to Mark Foundation Area

Foundation is the component of the structure which connects the structure to the ground. It bears the loads which are transmitted through the structural system of the whole building.

Types of Foundation

Foundation has two types. One is shallow foundation and another one is deep foundation. Spread footings, isolated footings are the example of shallow foundation. Piles, pile walls, and caissons are the example of deep foundation.

Purpose of Foundation

1. Foundation holds the building up.
2. It bears the load of the whole building.

The Process of Foundation

Floor plan

Level: Nor part of the floor is higher than anyone.

Square: Walls are parallel and the length of the walls remain the same.

Plumb: There are 3 steps

1. Orientation of the building on the site.
2. Mark a simple outline of the building’s foundation on the ground;
3. Place a batter board around the foundation outline and mark the position of the inside walls, doors, and windows on the boards.

Top 8 Ways to Save Money on House Construction

Are you planning on building your own dream home that you always wanted? Or are you renovating or upgrading your existing house? Either way, construction is an expensive task, made doubly difficult by the present home loan situation. So, here are the top 8 ways to save money on house construction.

Constructing new or upgrades is always costly, and you don’t get much say in this. But if you plan about your home building carefully and choose the right options, you can avoid a lot of expenses on design, construction, and maintenance. It is always good to be able to cut back on homebuilding costs. There are three main ways you can do this:

Reduce basic pre-construction expenses

• Avoid costly mistakes
• Cut back on maintenance

While those are the main three avenues of cutting costs on homebuilding, in practice you will have to give time and efforts a lot of small matters to optimize your house construction costs. The following are the top 8 ways to save money on house construction you can try among those.

1. The Devil is in the Details

Why pay for stuff you don’t really need? Most building contractors, or even designers, will try to push on expensive features on you that you won’t actually use. Why would you want some exotic vitrified tiles on your floor when you are perfectly ok with a simple mosaic? Don’t fall into sales traps.

Lap Length of Column, Beam and Slab

When the size of bars are short from their required length then lap length is necessary. When the diameter of the bar has to change along the length then the lap length is also required.

Purpose of using Lap Length

It is used to spread the axial force from the terminating bar to the connecting bar with the action in the junction. The effect of stress concentration should be minimized by using the splicing techniques, to keep the lapping locations away from the sections by the shear stresses.

Lap length according to the Indian Standard 456

The development length is 41d where d is the diameter of the bar. The lap length should be 2 Ld or 30d for direct tension. In this case, the straight length of the lapping bar should not be less than 15d or 20cm.

1. Type of lapping method
2. Lapping of bars
3. Welding of bars
4. Mechanical connection

Lapping of Bars

Lap splice is overlapped over a certain length and after that the axial force has to transfer from the terminating bar to the connecting bar through the mechanism of bond with the surrounding concrete.
