Bridge Aesthetics

Bridge Aesthetics




Aesthetics is essentially the quality of beauty and appeal to the senses. Some feel that in today’s machine age bridge need only be functional one, on similar lines then house may be defined as ‘Machine made for living in’ Wherever possible at least some margin shall be kept for enhancing the aesthetic quality of bridge. Attempt should be made to integrate its form with its landscape.
The bridge form should represent a fusion of art and technology. In the innovative structure design by great engineer-architects,the structural form and dimension of each component portrays musical harmony with mathematical exaction. Ruskin said that all forms of beauty are composed exclusively of curves and this is equally applicable to most bridges. Light and shade determine the depth of object, hence surface treatment can enhance the expression of bridge. Few characteristics / concepts discussed below comprise the principles of good aesthetic design.

5.2.1 PROPORTION
It is primary aesthetic objective. In relation to bridges, proportions may pertain to structure total, environment, elements of structure. Proportion between linear dimension like length, width, height, between masses / voids, areas in light / shadows are considered important. Choose optimal span / depth (L/D) ratio, choice is 5 to 20 or even 45 is feasible. In case of very flat, large, rectangular openings L/D > 20 may be opted. Preferably select odd spans with span length decreasing towards ends to give rhythm. Adopt wide cantilever width of deck slab for optimal ratio of areas lightened and in shadow.

5.2.2 CONTRAST
As opposed to harmony in proportions, it can lighten values of some elements in comparison with others. Contrast may be in volumes, material, colours, light, linear dimension etc.

5.2.3 SCALE
The absolute real dimension of structure defining its scale plays a dominant role in aesthetics. Scale of bridge is judged from different points of view.

5.2.4 ORDER
Order is key aesthetic quality in bridge. Order in lines is achieved by limiting their directions in space to the minimum practicable. Repetition of shapes leads an order which provides rhythm, however overdone repitions is to be avoided. Simplicity and cutting down unnecessary accessories leads to a good order. An uninterrupted line of fascia beam can emphasize the continuity of roadway flowing from one abutment to another.
As far as possible, avoid intersecting lines.Multiplicity of colours for a pier and /or large number of piers for long bridge with small spans leads to disorder. Avoid large number of equal spans for long bridge as it leads to monotony and uneasiness. Avoid sudden increase in support section like large well showing out of water.

5.2.5 CHARACTER
Character is an element of man made environment and expressed by its effect on the human using it. The structures today need to reflect technological excellence and look modern. Use of uniform depth beam for long river bridge with low clearance above water level produces stiffness. This can be broken by curved soffit. However, highly curved soffit with depth at centre disproportionately reduced, is unpleasant.

5.2.6 COLOURS
Colours have a significant effect and can attribute to balance and tension. However in bridges concrete being the material, choice is limited.

5.2.7 FUNCTIONALISM
In bridges form follows function. Functional efficiency never conflicts with form. It generates simplicity in form and aesthetic quality. Ornamentation of larger surface of piers, abutments, retaining walls by suitable surface treatment for texturing can give heightened aesthetic quality and character to a bridge especially in an urban environment.

5.2.8 ENVIRONMENTAL INTEGRATION
Integration of bridge structure with environment is most important need of modern bridges. Simplicity in form may suit open rural lands. Wider river crossing may demand bridges compatible with majesty of river. Structures built in urban environment should have special quality because it has large impact on people and their habitat. Very slender beams with stiff parallel faces on tall thick piers are incompatible with high mountain backdrop. A long bridge in hilly terrain should never be in straight alignment. It has to pickup movement of terrain.

5.2.9 COMPLEXITY
It is part of second order aesthetics. Complexity results from a deliberate disregard for order, harmony and symmetry. In short the simplicity of form and proportion with load masses in locations where most effective, makes pleasing appearance of bridge structure.

5.2.10 HORIZONTAL AND VERTICAL GEOMETRY
Aesthetics is a matter of taste and therefore it is not possible to codify the rules, which are to be followed in the Designs of bridges. However, few criteria like alignment (horizontal and vertical) with proper geometrics can add to the architecture of bridge. The approach gradients either for a valley curve or a summit curve shall have a continuity without break. The change of slope should be gradual without any abrupt or sudden change.

 The approach gradients with two vertical curves at two ends with the bridge deck straight is preferable to the kink. But a convex curved bridge deck in the vertical plane having a single curvature will be most preferable

This site is an attempt of mine to share the knowledge that I possess. It is said that "the more we share, the more we learn".Keeping this fact in mind, I have created this site and I hope it helps other students enrich their knowledge as well that of myself. 

Now a days a major problem in youth is the less in concentration in studies , My self SAURABH GUPTA me to suffering from same diseases .........


This blog is something different because here we discuss the problems in various subject and upload notes on various subject which enhance our knowledge and keep in touch with cousre as well as knowledge :)


Appeal all user to contribute notes and share as much as possible ...



EVEN semester notes .... plz friend contribute here

   Structure Mania
(16-17 feb 13 )

Structure Mania is an event that brings together hundreds of engineering students from vaired streams to participate in a full-day celebration. Young minds are challenged to design and build a popsicle stick bridge based upon given rules. Students submit their designed structure and then their strength are tested  using standard loading machine or an equivalent.
The competetion is a fun way for students to think critically, be innovative, learn to solve problems and to recognize the importance of higher education.




One man's "magic" is another man's engineering. "Supernatural" is a null word.

STRUCTURE MAKING

Structure Making  is an event that brings together hundreds of engineering students from vaired streams to participate in a full-day celebration. Young minds are challenged to design and build a popsicle stick bridge based upon given rules. Students submit their designed structure and then their strength are tested  using standard loading machine or an equivalent.
The competetion is a fun way for students to think critically, be innovative, learn to solve problems and to recognize the importance of higher education.

Materials to be used are popsicle stick, adhesive(fevicol), cobbler thread, paper pins and will be provided by organisers. However an individual team can keep sketch pen, sheets or other material for decoration purpose, these will not be provided by organisers.
A team of 2 to 4 enthusiastic people can participate with an entry fee 0f 200/- Rs. Per group.



-------------------------------------------------------------------------------------------------------------------
















10 questions.
Questions will be completely logical and brain teasing.
If you can really just wonder and feel the load, the way they acts on the bridge, here you are. 2. Bridge making
 You have to make a bridge using popsicle sticks, cobbler thread and adhesive.
The bridge constructed soon creatively, with maximum load bearing and lesser number of sticks may be the winner (plus OQP).
As time is sufficient with you, bridge with minimum sticks and maximum load will be the first preference.
The bridge with attractive design (look) may have bonus.
Though if there is quite significant difference in time of completion it may matter. 
Although few models prepared by organizers will be there for demonstration.
Sufficient time will be allowed for glue to freeze and stick properly.
Other directions will be given at the time accordingly.
