GSS2014 The Next City // day 2

admin — Thu, 10 Jul 2014 14:03:56 +0000

Today, day 2 of the Global Summer School, began the Analysis phase of the GSSBCN where building physicist and solar simulation expert Spyros Stravodavris got in depth with tools for simulating the energy potential of built structures.

In the coming days, participants will understand how to use these tools to calculate the energy potential for building sites and entire territories.

PRACTISE FABRICATION // LIGHTWEIGHT STRUCTURES 1:1 // day 1 to 3

admin — Sat, 10 May 2014 13:28:05 +0000

The Practise Fabrication // Lightweight Structures 1:1 Seminar, led by Silvia Brandi and Rodrigo Rubio, with the collaboration of Pepe Ballesteros (Prototipolab) and Maria Kupstova, is focused on the digital fabrication of lightweight 1:1 scale spatial installations, based on the expertise of Experimental Structures, and the further development of some concepts proposed in Public Space Capsules Seminar from Term 2.

The aim of the Seminar is to realize lightweight spatial installations (embedding textile materials) that are demountable, digitally fabricated, and eventually performative.

The students have formed 4 different groups, each one working on a different structural prototype implementation. In these first 3 days of the seminar each group worked their concept design, testing the structural capacities through the production of small scale prototypes.

The course counts on the collaboration of the company SERGE FERRARI, an international producer of flexible composite materials and membranes of high performances for architecture, who will provide the material for the construction.

ARNDT GOLDACK LECTURE – Dynamic Lightweight Structures

admin — Tue, 29 Oct 2013 21:26:57 +0000

Tonight we had the pleasure of hosting at IaaC a Lecture by TU Berlin Researcher Arndt Goldack as part of the Fall Term Lecture Series of 2013.

There is a trend in architecture and structural engineering towards more and more lightweight structures, as such structures are not only elegant but also minimizing the use of material. They are sustainable in the true sense. An inherent feature of lightweight structures is their tendency to be lively. Numerous exciting and breath taking structures such as membrane roofs, cable net structures and cable-supported footbridges have been built and they all require additional engineering efforts, regarding dynamics. Early lightweight footbridges have caused comfort problems for the users. Today engineers have learnt their lessons from several disasters and have included “dynamics” in the curriculum of engineering students. At our chair at the Technical University Berlin (TU Berlin) it has become an important research aspect. Beyond passive tuned mass dampers, investigation on semi-active vibration control will enable us to go beyond present limits towards more lightweight and elegant, more sustainable structures.

Dr.-Ing. Arndt Goldack was born in 1969 in Stuttgart, Germany. In 1996 he graduated in civil and structural engineering at the University of Stuttgart, and in 2004 Awarded Doctorate (Dr.-Ing.), Thesis “Structural behavior and Bracing of High Rise Tubes for Solar Updraft Towers”.

From 1996 to 2003 he was a Research assistant at the Institute for Structural Design with Prof. Jörg Schlaich and Prof. Werner Sobek, University of Stuttgart.

In 2003 he then commenced as Structural Engineer with schlaich bergermann und partner, Berlin, Stuttgart, until 2011. During this time he contributed to projects in China, Germany, India, Spain, USA:

- Stress ribbon bridge “Slinky springs to fame”, Oberhausen

- Membrane roof for Estadio Madrid La Peineta

- Gänsebachtal Bridge: Integral Bridge for High Speed Trains, length 1001m

- Cable Stayed Bridge crossing Yamuna River in New Delhi, India: span 250m

- Independent Review of the Second Vivekananda Bridge in Kolkata, extradosed bridge

- Lufthansa A380 Service Hall in Frankfurt

- Dynamic design of almost all footbridges by sbp

- Research Project: Design of Lightweight Footbridges for Human Induced Vibrations, Goldack et. al., JRC-ECCS 2009 in cooperation with University of Porto, TU Delft and RWTH Aachen.

Since July 2011 he has been a Researcher at the Chair of Conceptual and Structural Design, TU Berlin, studying the dynamics of bridges, pedestrian induced vibration, experimental modal analysis, lightweight structures, lightweight concrete, structural control.

ASSIGNMENT III Preshure Structure (Air-Water)

Exprimental Structures SEMINAR DEFINITION

Esta estructura kinetica se basa en los principios de la presion o no presion para ser simplemente un objeto sin volumen a tener una geometria variable en funcion del entorno.
se trata de una estructura hinchable ya que su elemento vertebrador son un conjunto de tubos que se enlazan para crear la estructura, estos tubos al recibir agua por ejemplo (llubia) hace que la estructura crezca iy cree con poca llubia un elemento como banco o con una llubia torrencial un refujui. por tanto lo podriamos considerar cono un organismo sin geometria definida todo dependiendo de lo que pasa en el exterior.

El proyecto se basa en la idea de crear estructuras animadas en este caso a traves de la accion del viento y agua; cuando esta entra en el interior de los tubos a traves de la diferencia de presion se generan un conjunto de cojines que se inchan y desinchan a modo de edificio performativo donde te puedes resguardar de la llubia o por otro lado sentarte como un banco.
Asi si imaginamos como se ve en el render una ciudad con este volumen imperceptible antes de llover (es plano) y crece con los agentes admosfericos.

La definicion se basa en 4 lineas paralelas dos a dos donde ponemos un conjunto de puntos estos se unen con el otro estremo creando lineas. Estas lineas se proyectan en cualquier supetrficie que pongas encima i se puede modificar el grosor ya que tinen pipes con slider. estas se ven intersectadas en la superficie y alli le desimos que encuentre los puntos medios
y en estos cree una esfera que se vera modificada por dos lineas que contienen puntos medios y en estos cree una esfera que se vera modificada por dos lineas que contienen puntos atractores simulando la llubia.

Lo podemos imaginar en un paisage natural donde empieza a llober y van pareciendo estas estructuras a modo de setar, creando paisage creando organismo…
