Learn To Read Structural Drawings: With Real Site Videos

This video talks about the different kinds of drawings that are followed for the construction of the building. In this video, you will learn what architectural drawing is, how it is useful and how to read the architectural drawing. You also learn about the structural drawings and how to read them.

This video explains how you can read electrical and sanitary drawings required for the construction of a building. In this video, you will learn how the wiring of a room is done. How the switches and the lights and power sockets are connected in a drawing. You will also learn how the distribution box looks like and you will learn how a keycard switch works. In the latter part of the video, you will learn how the pipeline is arranged in a bathroom. You will see how the soil and waster water pipelines are taken out of the building. You will also learn to read the fire hydrant drawings.

Footing is one of the major part of a building which transmits the loads from the building to the ground. This video describes how an isolated footing is designed (not the process). It also explains how its reinforcement is placed at the site.

Footing is lowermost part of the foundation constructed of brickwork, masonry or concrete for the purpose of distributing load over a large area. Footing is provided on the basis of nature of the soil.
Types of Footing
• Isolated Footing
• Combined Footing
• Raft or Strap Footing
Footing may be in square or rectangular in shape.

This video describes how the Shear Wall Reinforcement at the Site is placed. Hope this video was helpful. Cheers

In structural engineering, a shear wall is a structural system composed of braced panels (also known as shear panels) to counter the effects of lateral load acting on a structure. Wind and seismic[1] loads are the most common loads that shear walls are designed to carry. Under several building codes, including the International Building Code (where it is called a braced wall line) and Uniform Building Code, all exterior wall lines in wood or steel frame construction must be braced. Depending on the size of the building some interior walls must be braced as well.

A structure of shear walls in the center of a large building—often encasing an elevator shaft or stairwell—form a shear core.

Shear walls resist in-plane loads that are applied along its height. The applied load is generally transferred to the wall by a diaphragm or collector or drag member. They are built in wood, concrete, and CMU (masonry).

The tie beam is a terminology used for a beam whose 

function is not to carry the slab load but just to act as a
stiffner to the columns and thereby reduce the long column
effect. Sometimes it also acts as a damp proof course at
the plinth level and as a seperator for ventilators and
doors when placed at the lintel level.

This video explains how you can read the drawings of column stirrups. Column stirrups are the lateral ties that hold the vertical rebars together.

This video explains how you can do ductility detailing of column. Ductility detailing is very important while placing the rebars at the site.

This video explains how the reinforcement of the staircase is detailed. This video shows the reinforcement of staircase from the footing level. It shows the reinforcement of both the open well and dog-legged staircases.

Shear wall is a structural member used to resist lateral forces i.e. parallel to the plane of the wall. For slender walls where the bending deformation is more, Shear wall resists the loads due to Cantilever Action. In other words, Shear walls are vertical elements of the horizontal force resisting system.

In building construction, a rigid vertical diaphragm capable of transferring lateral forces from exterior walls, floors, and roofs to the ground foundation in a direction parallel to their planes. Examples are the reinforced-concrete wall. Lateral forces caused by wind, earthquake, and uneven settlement loads, in addition to the weight of structure and occupants, create powerful twisting (torsional) forces. This leads to the failure of the structures by shear.

Shear walls are especially important in high-rise buildings subject to lateral wind and seismic forces. Generally, shear walls are either plane or flanged in section, while core walls consist of channel sections. They also provide adequate strength and stiffness to control lateral displacements.

The shape and plan position of the shear wall influences the behavior of the structure considerably. Structurally, the best position for the shear walls is in the center of each half of the building. This is rarely practical, since it also utilizes the space a lot, so they are positioned at the ends. It is better to use walls with no openings in them. So, usually, the walls around lift shafts and stairwells are used. Also, walls on the sides of buildings that have no windows can be used.
