32-66 CONSIDERAȚII PRIVIND IMPACTUL DINTRE UN PARAPET DE PROTECȚIE ŞI UN PENDUL

CONSIDERATIONS REGARDING THE IMPACT OF A PROTECTIVE BARRIER AND A PENDULUM

 

The paper presents the impact of a pendulum with a weight of 2780 kg and a road protective barrier used on the roads of Romania. Deformable parapets are very important to protect the pedestrians and the vehicles on our roads. The maximum dynamic deflection of the parapet, measured after the test was 0,240 m and 0,435 m of working width.

The barrier was deformed as expected. Damping elements have taken a large amount of energy during impact. The pendulum is used by researchers in this field. This is a very good way to track the behavior and damping elements of the barriers in the laboratory.

At the beginning of last century, Romania was one of the richest European countries, among the first 10 countries that have introduced the car since its inception.

It presents the first transport vehicles in Romania dates back to 1895 are represented by two hybrid trucks with steam. „The Karaso” Simplon exotic convertible is a car made in Resita, in the style roadsters from the 50s. Vintage cars are not just cars, they can be considered on its own history on wheels, ideal combination for nostalgic times in which power was aesthetics, elegance and refinement. The oldest car in the west is a nice Ford Model A, 1928. The tradition left by the big names in automotive construction must be respected, promoting the work of some young Romanian students from technical universities and their achievements: University „Ovidius” in Constanta, Technical University „Gh. Asachi” University and University of Pitesti.

ABOUT ELEVATORS (LIFTS). LIFTS FREE CABLE
The current system is inefficient elevators and limiting cable with a
fairly large footprint and requires people to wait a long time for the next
elevator. Recently, the German multinational ThyssenKrupp Corporation
introduced a revolutionary concept of elevator multi-cabs without cables, which
shorten long waiting in tall buildings. And it can be used not only for vertical
movement, and for horizontal movement. The proposed system is similar to a
railway subway could integrate several cabins propelled and running in a loop,
passenger transport is ongoing in several cabins, thereby reducing waiting time
and can offer passengers access a lift every 15 seconds. Thus, the space
occupied by elevators can greatly reduce transport capacity can increase,
achieving savings in energy consumption.

Profound rethinking the whole educational system, focusing on training is an absolute priority. The negative effects of climate change are already beginning to be felt all over the world. States are still poorly prepared for the huge potential impact on food security, water supply and human health, that. Global warming could undermine economic growth and could increase poverty.

25-74 CONSIDERAȚII PRIVIND LĂȚIMEA DE LUCRU A PARAPETELOR LA IMPACTUL CU O SFERĂ

CONSIDERATIONS REGARDING THE WORKING
WIDTH OF ROAD RESTRAINT SYSTEMS AT
THE IMPACT WITH A SPHERE
This paper presents the simulation of the behaviour of two types of
road restraint systems on impact with a sphere in different points from the pillar
axis. The working widths of the restraint systems during collisions are
presented. The working width is very important because it characterizes the
parapets during impact. The simulations were performed with the help of finite
element software using Altair Hyper Works modules.

BRIDGE BUILDING, part II
The bridge is a construction of category artworks, intended to
overcome an obstacle (the River, a Valley inland communications) moving
above them, being built over the immense valleys, across streams or linking the
Mainland and the island. Bridges, is an obsession of the writer Ivo Andrić; his
work, „it’s a bridge on the Drina” recounts the history of the Şokolovici bridge
traditional Mehmed Pasha, from Visegrad, Bosnia.
A bridge with a length of 1,380 m (30 m longer than the famous
Golden Gate in San Francisco), was inaugurated on august 19, 2013 in
Norway. Work on the bridge began in august 2009 and were completed in April
2013.
Galata bridge is a historic symbol of Istanbul today. He is one of the
great hearts, a vital link between the capital of old, old Constantinople and the
„new tow\” in Turkish, meaning city of merchants, banks and foreign diplomats.
The two distinct parts, the european Bank of the former Byzantine and Ottoman
capitals are the waters of mirificului Bay. The paper presents constructive who
built from 1453 to the present.
In 1502, Leonardo da Vinci’s drawing of a bridge has done „in one
piece”, 240 m, as part of a civil engineering project for Sultan Bayezid II Bridge
ought to be placed at the „mouth” of the Bosphorus, over a canal known as the
Golden Horn (Golden Horn). But no continued project B because he considered
such a construction impossible. The modern history of this unique bridge began
in 1996, when Norwegian artist Vebjorn Sand has seen the drawing shown in
the exhibition and acknowledged the „grația and the eloquence of Mathematics”
and proposed structure of the Norwegian public roads Administration to carry
out the construction. Leonardo’s bridge, built in Oslo in 2001, is a pedestrian
157
bridge and is the first civil engineering made after drawings by Leonardo da
Vinci.
In the past two decades, with the help of an intensive research
activities, they built bridges on roads, pedestrian or bicycle paths. Wood is a
very good building material, has good aesthetic appearance. The largest wood
bridge is the bridge in Vihantasalmi in Finland. The bridge has the largest span
is built from lakes Lahnavesi and Juolavesi and replaced by a construction
bridge. Was given in 1999.

AN IMPRESSIVE ENGINEERING WORK.
SAINT GOTHARD RAIL TUNNEL – SWITZERLAND
In the last 25 years, the segment between Lugano and Zurich, the
traffic of trucks has increased 12 times. For the purpose of streamlining
transport and for the expansion of the Swiss rail network, because each year
through the tunnel will pass 6 million passengers and 50 million tons of cargo,
after 10 years of studies and 15 years of construction, materialized construction
of Saint-Gothard tunnel.
What is Saint Gothard?
1. Mountain range in the Alps Lepontine (Switzerland, max. 3,192 m),
consisting of crystalline, Granites South and streets. 2. Pass from long, 26 km,
located at 2,108 m altitude, on the border with Switzerland and Italy, which
provide the link between the two countries in the area of Reuss and Ticino
valleys. 3. Rail Tunnel, located 1,154 m high, built in the years 1872-1882,
between the villages of Airolo (Italy) and Andermatt (Switzerland), assigned for
a distance of 15 km from the Saint-Gothard. 4. Road tunnel, 16.3 km long,
opened to traffic in 1980, ensuring links between the settlements of Airolo (Italy)
and Andermatt (Switzerland). 5. The longest rail tunnel in the world, which
should enter into service in the year 2017, the core piece of the expansion of
the Swiss rail network.

se dirige vers l’Irak à l’est. L’Euphrate fournit à la Syrie sa plus importante
ressource hydrique: environ la moitié du total de ses ressources renouvelables
estimées à 23 milliards de m3 pour une année hydrique moyenne. Trois
barrages ont été érigés: le barrage d’Al-Thawra à Tabqa et les deux barrages
régulateur Tishrun, en amont, et Al-Bath, en aval, de nature hydro-électrique.
Les barrages permettent la production de l’énergie électrique (2,5 milliards de
