Project 2: Understanding Forces in Solid Structure and Surface Structure

The objectives of this project are as follows: • To create an understanding of solid structure and surface structure and its relevant structural components. • To understand how a solid structure and surface structure reacts under loading. • To demonstrate a convincing understanding of how Solid Construction and surface construction works. • To exploit the qualities inherent in Solid Construction and surface construction. • To be able to manipulate Solid Construction and surface construction to solve an oblique Design problem.

BUILDING ANALYSIS

>> CONSTRUCTION PROCESS

Erection of the cupola’s steel

framing begin in June 1997

and the completed in Septem-

ber 1988.

The rst step was construction

of a temporary steel formwork

on which the ramps were sup -

ported during their assembly.

With the ramps in place, the

meridian structural ribs were in-

stalled; in the completed struc-

ture the ramps are suspended

from these ribs.

Mounted externally onto the ribs

are the horizontal ring beams

that support the glazing.

Spaced 1.7 meters apart, the

beams are secured to the ribs

by means of cast steel brack -

ets.

The structural elements that make up the

cupola were fabricated in the workshops

of Waagner-Biro in Vienna throughout the

spring and summer of 1997.

The ramps were fabricated in short sec-

tions to facilitate transportation and weld-

ed together on site to form continuous

lengths.

pletion.

The fast glazed panels are lifted in place.

The mirros that line the cone were se-

cured in place and adjusted individually to

ensure optimum efciency.

CONCLUSION

Upon reection, the project was very useful in helping us understand the way surface structure construction works. There were a number of setbacks as high -

lighted in the previous pages, but overall, the main difculty was in the extortionate amount of details in the construction.

The spheric nature of the building also left no room for second guesses. Calculations had to be made down the the position of holes and the degree of curva-

ture. The sheer volume of individual components was also overwhelming and demanded the most man power out of all the tasks.

Precision is key in assembling this project and is the reason for most of failures during the trial period. There were numerous other issues but we managed to

overcome them.

Though the model construction process was not a failure in any sense, there are still numerous ways in which they could have been improved. Perhaps a deeper

understanding of the material was needed in order to maximize results.

Precision could have been improved in terms of execution. On paper everything looks ne but it is onlu I when making the model do problems start cropping up.

For future reference, if budget permits, perhaps laser cutting components would help increase the accuracy.
