How to carry out a cube test?

Steps to carry concrete cube testing

1. Mix the concrete as per ur design mix

2. Pour to test cube mold, dimensions of 150x150x150mm and the use hand vibrator to conpact it

3. Take siz sample of this cube.

4. Test 3 sample on 7 days, check if you have recive 70% strength from your deaign mix

5. Test remaining 3 samples on 28th day and see if you have achived your design strength.

Types of loads explained

There are different types of loads that act on a building structure, depending on the nature, magnitude, and direction of the forces. These loads can be broadly classified into four groups: dead loads, live loads, impact loads, and environmental loads.

- **Dead loads** are the constant loads that result from the self-weight of the structure and its permanent components, such as walls, floors, roofs, ceilings, etc. Dead loads are calculated by multiplying the density of the material with the dimensions of the structural element.

- **Live loads** are the variable loads that result from the occupancy and use of the structure, such as people, furniture, equipment, vehicles, etc. Live loads depend on the function and location of the structure and are usually specified by codes and standards.

- **Impact loads** are the sudden or dynamic loads that result from the application of a force over a short period of time, such as moving vehicles, vibrating machinery, dropped weights, etc. Impact loads cause larger stresses in the structure than those produced by gradually applied loads of the same magnitude.

- **Environmental loads** are the loads that result from natural phenomena or human activities that affect the structure, such as wind, snow, rain, earthquake, temperature, fire, etc. Environmental loads vary in intensity and frequency depending on the location and climate of the structure.

Types of loads on a structure beams

Point load; its when u have a load acting on a certain point, example as above.

Uniform distribution load; its when u have a load laying across the beam, such as a wall.

Triangular distribution load; it can be a load that is heavy at one side, for example roof or a container on a truck whihc is half loaded.

TYPES OF LOAD that can act on a building

As explained above, building have its own materials weight acting on it and refer as dead load.. than you have live load, for example human being walking around n humping around, these loads acts mostly to gravity and knws as vertical loads.

Horizontal loads are more natural causes unless your building been hit by a bus.

I hope this answer helps you understand the types of loads on a building structure. 😊

MWSC water meter trench details

For Male city of Maldives there is only one compnay who supply clean water to houses which is called MWSC (male water and sewage company) 

Basically they need a trech that can connect all main connections to domestic and commercial meters, it can either be in concrete or other. Width 20 inch (500mm) depth of 18 inch (450mm) and average distance between each meter to be 150mm apart.

once this meter trech is complete they will come and do a site survery and install water meters for usage.

How to design a stair for a exsisting site

It is a challenging thing that the actual site and drawings doesnt match.. so lets see the steps i follow in order to get a stair case right on spot to go to top floor.

first took the measurements of tge opening on the top floor.. length and width. Measured with a measuring tape on site ans drew on picture so that later when i go to office ill know what im doing.

too the slab thickness and floor height from top to top.. so that its easy to find no of steps required. 

Than took a pic from below floor so that i can visualize when i go back to office.

above is the desing whihc came best for the place, did some autocad drawing and this whats it looks like, than next is fabrication time at workshop

by using 100x50mm square hollow section made the main frame and steps with 50x50mm angle pcs.. step is 50mm thick solid wood.

 installed.. looks good   now its time to screw the wood steps and your all set to go uptge stairs.

time to deisng mezaarine to ground level as well

First we took a bench mark of 1m from the out side finishing level.. than marked it on the wall below the mezzanine floor. From that didba scale design.

fabricated it in our workshop.
