- 4. INTRODUCTION TRABEATED STRUCTURES • In architecture, post and lintel (also called prop and lintel or a trabeated system) is a building system where strong horizontal elements are held up by strong vertical elements with large spaces between them. • This is usually used to hold up a roof, creating a largely open space beneath, for whatever use the building is designed for. • The horizontal elements are called by a variety of names including lintel, header, architrave or beam, and the supporting vertical elements may be called columns, pillars, or posts. The use of wider elements at the top of the post, called capitals, to help spread the load, is common to many traditions.
- 5. INTRODUCTION The vertical elements are called posts The horizontal element is called lintel.
- 6. INTRODUCTION The horizontal distance between two posts is known as the span
- 7. INTRODUCTION LOADS AND COUNTER LOADS
- 8. INTRODUCTION The post and lintel structure is subjected to two kinds of loads:- i) Live load – It is the load by external forces e.g. Air pressure ii) Dead loads – It is the load the structure bears due to its own weight of its materials

- 21. TRABEATED STRUCTURES IN GREECE • Classical Greek temples used the basic post- and- beam construction, which is referred to as trabeated. • All the types of Greek temples had the colonnade as the basic element of the temple; mostly surrounding the 'naos’of the Greek temple. ANCIENT TRABEATED STRUCTURES 21
- 22. PLAN OF A GREEK TEMPLE • The grandeur and evident expense of a temple can be seen in the number of columns employed. • An open area or porch in front, with supporting columns. • Dipteral temples have double colonnade surrounding them. • Peripteral temples (Parthenon) have both back and front porch as well as a colonnade surrounding the entire structure ANCIENT TRABEATED STRUCTURES 22

- 33. SITE PLAN AND GF PLAN • The ground floor of the Farnsworth House is thereby elevated, and wide steps slowly transcend almost effortlessly off the ground, as if they were floating up to the entrance • Aside from walls in the center of the house enclosing bathrooms, the floor plan is completely open exploiting true minimalism. TRABEATED STRUCTURES IN MODERN ARCHITECTURE
- 34. SECTIONAL DETAILS • The single-story house consists of eight I-shaped steel columns that support the roof and floor frameworks, and therefore are both structural and expressive. • In between these columns are floor-to-ceiling windows around the entire house, opening up the rooms to the woods around it.

- 43. PLANNING OF THE MUSEUM • A pavilion-like volume is located on the highest terrace, providing the entrance to the museum. • The interiors of the museum reveal themselves as one descends down through the loggia, foyer and staircase spaces. • The dark timber-panelled exhibition galleries are illuminated only by artificial light due to fragility and sensitivity of the works on display. • Each of these environmentally controlled spaces borders onto a naturally lit gallery, balancing views inward to the composed, internalized world of texts and manuscripts with the green and scenic valley on the other side of the glass.

- 45. ELEVATION Since the museum is located on a rock plateau, the site has a varying topography. In order to complement the contours of the site, the museum has been built on two distinct levels. Embedded in topography, the museum reveals a single height elevation to the north and a double height elevation to the south. The steep slope of the site creates an intimate, shaded entrance on the brow of the hill facing the Schiller National Museum, the forecourt, the park and the grander open tiered spaces on the valley bellow it. On the highest terrace, the building appears as a pavilion, providing entrance to the museum. THE BUILDING REVEALS SINGLE HEIGHTED ELEVATION IN THE NORTH AND DOUBLE HEIGHTED ELEVATION IN THE SOUTH LITERATURE STUDY : DAVID CHIPPERFIELD LITERATURE MUSEUM, AM NECKAR
- 46. Slender concrete columns articulate the façade and enclose the entrance. Once inside, the visitors work their way down the grand series of stairs(owing to the contours of the site) into the exhibition spaces, which consists of a sequence of five galleries. The galleries are timber-lined with richly coloured wood and connected to the naturally lit, glazed loggias, connecting to the world of manuscripts and texts to the valley beyond. ON THE HIGHEST TERRACE THE BUILDING APPEARS AS A PAVILLION PROVIDING ENTRANCE CONCRETE COLUMNS ARTICULATE THE FACADE LITERATURE STUDY : DAVID CHIPPERFIELD LITERATURE MUSEUM, AM NECKAR
- 47. ANALYSIS The space between the façade articulated by concrete columns and naturally glazed loggias, witnesses amazing play of light and shadow, as the glass too reflects the pattern. It locates a comfortable double heighted circulation space around the functional area. Since the columns are placed at a good distance from each other, it not only forms a sturdy structure with less number of structural elements, but also allows huge expanse of glass to be accommodated on the main skin of the building, which lets in more light.

- 48. The façade is made to cut off direct light and preserve the fragile manuscripts. As the building is built to complement the contours of the site, it exhibits variation in datum levels. The columns on the façade generate rhythm. The building thus creates an incredible fusion of ancient Egyptian, Minoan and Greek form with a more subtle modern form.

- 52. PRINCIPLES AND PHILOSOPHY • A clearly defined material concept using solid materials (fair-faced concrete, sandblasted reconstituted stone with limestone aggregate, limestone, wood, felt and glass) gives the calm, rational architectural language a sensual physical presence. • The museum is located in Marbach’s scenic park, on top of a rock plateau overlooking the valley of the Neckar River symbolizing the fall and rebirth of Germany through the dark ages of the World Wars and its re-emergence as a stronger and an economically strengthened country. • As the birthplace of the dramatist Friedrich Schiller, the town’s park already held the National Schiller Museum, built in 1903, and the Archive for German Literature, built in the 1970s. And hence the creation of light and shadow pattern to enhance the drama.LITERATURE STUDY : DAVID CHIPPERFIELD LITERATURE MUSEUM, AM NECKAR

The jetty is mainly used by the Indian Navy. CASE STUDY: PRINCEP GHAT
- 59. ABOUT THE STRUCTURE Architect, Captain W. Fitzgerald built the colonial monument Princep Ghat in memory of James Princep. The Palladian porch has been designed with rich Greek and Gothic inlays. Six ionic columns lines each of the two side facades and two ionic columns lines each of the two shorter sides. There are a total of 4 rows of ionic columns that support the entablature above. The ionic columns have fluted shafts. It has a rectangular plan. At the four corners there are projections, having thick walls. Towards the outside they bears arches supported on Ionic pilasters, also the projections have been cut out such that they provide a platform for sitting. CASE STUDY : PRINCEP GHAT
