CHAPTER 3
STRUCTURAL MODELLING
3.1 OVERVIEW
This chapter gives an overview about the structure detailing of the building, material properties, loads considered and basic assumption of the building considered, in the present study. In structural designing it is important to prepare a systematic model of the building in which proper beam column arrangement are prepared. This chapter deals with basic assumptions taken in the study.
In this chapter detailed study of G+3 RCC frame building modelled with fixed support is presented and the type of building model considered.
3.2 BUILDING DESCRIPTION
Type of building usage considered in the present study is a residential building. The building is supposed to be at Uttrakhand, India in seismic zone 4.

Live load is taken 2kn/m2. According to IS1893:2002 seismic weight of the building is taken as Dead load+25% for live load up to 3kn/m2 and if live load is larger than 3kn/m2 than dead load +50% of live load. Apart from this self-weight of beam and column, infill weight and parapet weight are considered.

First one is in which brick masonry is the load taken members, which are obsolete now days and in the second type reinforced concrete frame structure is constructed and the brick masonry wall is used as a packing carnal. Construction of the building by using the first method is only reliable when the building has to resist only vertical loads. But frame type system is suitable for the resisting of vertical as well as horizontal load. In the earthquake lying down area frame structure buildings are constructed from the safety point of view. A frame structure (building) is considered in the present study and in which beam and column are modelled. Beam and column joint is the important factor in the RC frame. Beam and column joint is the portion where the column and beam intersect at each other. Large forces are develop in the joint at the time of the earthquake which affects the counter of the building. In the conventional design of practice check for the beam column joint is not critical, but for the seismic point of view it is necessary to check the joint. In the study beam –column joints are taken as rigid joints. The basic need of the joint design improves the shear strength of the joint. Beam column joint are of three types, interior joint, exterior and corner

The key to GFRC is the glass-fibre reinforcement. The glass fibres take the place of steel in a wet-cast mix, which allow GFRC to develop much greater strengths than standard wet-cast concrete. This then allows us to cast thinner, lighter sections but also larger in surface area if need be than ordinary reinforced concrete panels.
Brooklyn Bridge The Brooklyn Bridge was crucial to the future of bridge building and is spectacular. The bridge connects the boroughs of Manhattan and Brooklyn in New York City. It was built by John Roebling, an amazing architect, and it was the longest suspension bridge ever constructed at its time. This is part of the reason why the bridge is so amazing.
In July 19, 1936 Richmond Times-Dispatch’s Sunday magazine and book review section published the picture above depicting what’s the history of the Egyptian building medical college of Virginia: Egyptian building, Medical college of Virginia . The Egyptian Buildings lies on 1223 E. Marshall Street, built in 1844. The building was originally built for the Medical Department of Hampden-Sydney College which in 1854 became an independent entity; the Medical College of Virginia (MCV).It was famously designed by Philadelphia architect Thomas S. Stewart (1806-1889) which still is considered one of the finest extant samples of the rare “Egyptian Revival” style, marking itself as a landmark in Richmond. In 1938-39, the Richmond architectural firm of
The column dimensions were 10 in. in the north-south direction (denoted as y-direction on the confined concrete column cross-section) and 15 in. in the east-west direction (denoted as x-direction on the confined concrete column cross-section). A concrete cover of 0.75 in. was used on all sides of the confined concrete column. Eight ASTM A706 Grade 60 #7 deformed steel bars were used for the longitudinal mild steel reinforcement bars inside the confined concrete of the column.
In her essay “The Home: Rancho Santa Fe and Suburban Style,” Phoebe Kropp discusses the emergence of the Spanish colonial style in Southern California. This architectural style became the signature style of this region as many communities began to build that architecture. Kropp uses the San Diego community of Rancho Santa Fe to argue how this style has been taken advantage of by Anglo American’s as they have used it in their modern communities. Kropp addresses that while these communities have adapted the Spanish colonial architectural style they have also created a discriminatory community where not all of the Spanish history and culture are being included and welcomed.
The Beam Bridge is simple and very inexpensive. A beam bridge consists of a horizontal beamthat is supported at each end by piers. The weight of the beam pushes straight down on thepiers. The beam has to be very strong so it doesn’t bend when added weight is applied. One ofthe disadvantages of the beam bridge is that it’s not the best type of bridge for long distances.
Your first stop will be The Parliament Building, which is a historical, beautiful and elegant building. It is a Romanesque Revival style building which is very popular right now, it is being a landmark and a symbolic building in Victoria. The Parliament Building is located in Victoria, Belleville Street. The roofs on the building is a unique design, they are round, which can ventilate especially in the humid wether in Victoria. This is why The Parliament Building has been called “The Birdcages”.
Austin Barrett Gosia Gabrys English 1110.02 27 Oct 2015 Analysis of Cathedral The narrator of Raymond Carver's short story Cathedral starts by saying, "This blind man, an old friend of my wife's, he was on his way to spend the night. "The narrator continues to say that after the blind man's wife died while visiting her relatives in nearby Connecticut, he had called the narrator's wife to arrange a visit of old friends. The narrator admits he is not excited about this man coming to visit his wife.
I had first formal exposure to civil engineering in course “Architecture 1”. This course provided me the fundamental concepts of civil architectural principles such as designing procedure, architectural component’s layouts, functional spaces as well as environmental impacts. To strengthen my concepts I pursued the courses “Strength of Materials”, “Structural Mechanics” which gave me essential knowledge about the external and internal forces occuring in simple structural elements under action of various types of loading as well as fundamental concepts in structural analysis such as modellisation, classification of structures. I gained valuable exposure to the analysis of simple structures submitted to compound loadings by the application of the principle of superposition for such cases as: unsymmetric bending, combined bending and tension or compression, combined bending and torsion, general compound loading. Futhermore, I was fascinated by the force method and displacement method for analysis of statically and kinetically indeterminate structures.
Frank Lloyd Wright is considered to be the pioneer of modern architecture. He created an identity for American architecture, while rejecting Neoclassical and Victorian style designs. Wright called this “organic architecture”. It is architecture that is simple, yet modern and co-exists with architecture. He provided a new perspective on architecture and “The American Style”.
But it is not actually a single piece structure, but is made by welding several parts together. Advantages are that automation can be easily done, making it feasible for mass production. Since a large amount of metal is used in the construction, a Crumple-zone can be incorporated into the design. Disadvantages include its weight, due to the large amount of metal used. Space-Frame and a Monocoque are suitable for the current application.
Walking up to the magnificent La Pedrera building the first thing I had to see was the pillar known as the elephant's foot. This pillar is notorious and was mentioned in the reading due it occupying too much space on the sidewalk of Passeig de Gracia. During construction Gaudi was informed of this by the government and told to make modifications, but Gaudi wouldn't budge. He wrote a letter back to the government and stated that if he were to modify the pillar, he would include a mocking inscription that would be-little the government. Fortunately the government rethought their demands and the pillar wasn't changed but this small aspect of the construction process I find awesome.
Tectonics is defined as the science or art of construction, both in relation to use and artistic design. It refers not just to the activity of making the materially requisite construction that answers certain needs but rather to the activity that raises this construction as an art form. It is concerned with the modeling of material to bring the material into presence - from the physical into the meta-physical world (Maulden, 1986). Since tectonics is primarily concerned with the making of architecture in a modern world, its value is seen as being a partial strategy for an architecture rooted in time and place therefore beginning to bring poetry in construction. Tectonics, however, has the capacity to create depth-ness of context resulting in the implicit story being told by the tectonic expression.

Cracks are expected at intervals in this slab (Usually .90 to 1.2m) and are held together with structural steel. Appropriate spacing between cracks must be determined in order for this method to work. Continuously reinforced roads can sometimes be more expensive than the other two methods due to the higher quality of steel used in its construction, however this can be lowered by the reduced amount of cement used in the concrete mixture due to the thinner layer of concrete in comparison with the other two methods. With proper management, this method can be similar to the other two in terms of durability and cost
