What’s all the fuss about? A man assaults Rihanna (or possibly rapes her), so she shoots him.

Rihanna’s new video for the song “Man Down” starts with her shooting a man. Whoops, I guess I just gave away the plot. Anyway, it didn’t take long before groups like the Parents Television Council ripped the video. Basically, their point is that Rihanna is a role model and this video sends a message that killing someone is an acceptable form of revenge. Rihanna‘s response after you watch the video below.

Rihanna‘s response to her critics: she tweeted, quote, “I’m a 23-year-old rock star with NO KIDS! What’s up with everybody wanting me to be a parent?”

Another tweet reads, “The music industry isn’t exactly Parents R Us! We have the freedom to make art, LET US! It’s YOUR job to make sure they don’t turn out like US.”

Kap Shui Mun Bridge

Bridges, Civil Engineering, Construction, Engineering, Hong Kong

The Kap Shui Mun Bridge (KSMB) in Hong Kong was the longest cable-stayed bridge in the world that transports both road and railway traffic (superseded by Oresund Bridge in 2000, with a 490m main span), with the upper deck for motor vehicles, and the lower deck for both vehicles and the MTR. It has a main span of 430 metres and an overall length of 750 metres. It spans the main marine channel, Kap Shui Mun, between Ma Wan and Lantau and provides vertical clearance of 47 metres above sea level.

Span Lengths 

The bridge was completed in 1997. The total length of the Kap Shui Mun Bridge includes a 70 m approach span on the Lantau side. A column in each of the back spans of the cable stayed bridge makes four 80 m spans to add to the 430 m main span. This brings the total length to 820 m. The 503 m Ma Wan Viaduct was constructed under the same contract as the KSMB. The viaduct connects the KSMB to the Tsing Ma Bridge, thus forming the Lantau Link that was built to provide access to the new airport.^[2] The navigation clearance of 47 m is part of the reason that the H-shaped towers are 150 m tall.

The Kap Shui Mun Bridge is not symmetrical in that the 160 m back span length (80 m + 80 m) is less than half of the main span length (half of 430 m is 215 m). To provide the balance that symmetry will normally provide, the bridge has composite cross sections. The central 387 m of the main span uses steel composite with concrete to make the cross section lighter. The back spans and the remaining main span are concrete cross sections. Using the lighter steel cross section in the majority of the main span serves to equalize the horizontal forces on the towers and balance the bridge.

Because the lower deck carries both rail and traffic, the cross section is designed as aVierendeel truss. This means that there are no diagonal members in the cross section and that vehicles and rail cars drive through the openings provided by the Vierendiel design.

The Tsing Ma Bridge, which spans 1377m across the busy Ma Wan Channel, is the second longest bridge in the world after the Humber Bridge in Britain. However, it is the longest bridge that carries both motorway and railway.

There are Five Major Components
in the Construction of the Tsing Ma Bridge:

1. Foundations and the construction of the bridge tower – one tower located on Tsing Yi side and the other on a man-made island 120 m from the coast of Ma Wan Island. Both towers are 206m above sea level and founded on relatively shallow bedrock. The towers are two-legged with trusses at intervals, in the form of portal beam design. The legs were constructed with high-strength concrete of 100 MPa strength, using a slipform system in a continuous operation.

2. Anchorages – the pulling forces in the main suspension cables is taken up by large gravity anchorages located at both ends of the bridge. They are massive concrete structures deeply seated on bedrock on the landside of Tsing Yi and Ma Wan island. The total weight of concrete used in the two anchorages is about 300,000 tonnes.

3. Main cables – The cables were constructed by an aerial spinning process. The process involved drawing wires from a constant-tension supply, and pulling loops of these wires from one anchorage to the other, passing a 500-tonne cast-iron saddle on top of each bridge tower seating the cable. A total of 70,000 galvanised wires of 5.38 mm diameter were placed and adjusted to form the 1.1 m diameter main cable.

4. Suspended deck – The steelwork for the deck structure was fabricated in Britain and Japan. After delivery, they were further processed and assembled in Dongguan of China into standard deck modules. A total of 96 modules, each 18 m long and about 480 tonnes in weight, were prepared. These deck modules were brought to the site by specially designed barges and raised into the deck position by a pair of strand jack gantries that could manoeuvre along the main cable.

5. Approach span on Tsing Yi side – similar in form and cross-section to the suspended deck, but the approach span was supported on piers instead of cable-support. The first span was assembled on the ground and raised into position using strand jacks. Further erection then proceeded in cantilever in smaller sections, using derrick cranes stationed on the deck level. An expansion joint which allowed for a maximum thermal movement of 850 mm was also provided and located inside the approach span section.

The Tsing Ma Bridge was designed to carry two three-lane carriageways on the upper deck and two railway tracks on the lower deck. There are also two sheltered single-lane carriageways on the lower deck for maintenance access and as backup for traffic during typhoons when wind speed is still within acceptable limits. The construction cost of Tsing Ma bridge is $7.14 billion and the actual completion time was 57 months.

Ting Kau Bridge

Bridges, Construction

Ting Kau Bridge: is a 1,177-metre long cable-stayed bridge in Hong Kong that spans from the northwest of Tsing Yi Island and Tuen Mun Road. It is adjacent to Tsing Ma Bridge which also serves as major connector between the Hong Kong International Airport on Lantau Island and the rest of Hong Kong. It was completed in 1998. The bridge is toll-free.

 

 

 

 

 

 

 

 

The bridge is part of Route 3, connecting North-west New Territories with Hong Kong Island. Other major infrastructures on the road includes Tai Lam Tunnel, Cheung Tsing Tunnel, Cheung Tsing Bridgeand Western Harbour Crossing. Compared to the nearby bridges on Lantau Link, Ting Kau Bridge is not just a landmark structure but also carries the heaviest traffic volume of the bridges, with many container trucks travelling to and from mainland China and the HK container port. A chromatic study and specially designed architectural lighting are intended to set the bridge off in its surroundings.

Ting Kau Bridge is the world’s first major 4-span cable-stayed bridge. This meant that the central tower had to be stabilised longitudinally, the problem being solved using the longest (465 m) cable stays ever used in a bridge. The design of this bridge contains special features such as single leg towers, which are stabilised by transverse cables just like masts of a sailboat. The Ting Kau Bridge and approach viaducts link the western New Territories and the mainland to an expressway called Lantau Fixed Crossing, which connects the new Airport with Kowloon and Hong Kong. It meets the Lantau Fixed Crossing on Tsing Yi Island only 500 m from the Tsing Ma Bridge.

The Ting Kau Bridge and Approach Viaduct are 1,875 metres long while the triple tower bridge has an overall length of 1,177 metres. Three towers have been specially designed to withstand extreme windand typhoon conditions, with heights of 170 metres, 194 metres, and 158 metres, located on the Ting Kau headland, on a reclaimed island in Rambler Channel (which spans 900 metres wide) and on the north-west Tsing Yi shoreline respectively.

The arrangement of separate decks on both sides of the 3 towers contributes to the slender appearance of the bridge while acting favourably under heavy wind and typhoon loads. Each deck carries 3 traffic lanes and a hard shoulder.

At a design & construction cost of HK$1.94 billion, it is one of the longest cable-stayed bridges in the world. Along with the Tsing Ma and Kap Shui Mun bridges, it is closely monitored by the Wind and Structural Health Monitoring System (WASHMS).

Ting Kau Contractors Joint Venture designed and built Ting Kau Bridge between 1994 and 1998. The joint venture comprised lead partners Cubiertas Y Mzov (22%) and Entrecanales Y Tavora (22%), both of Spain (now both part of Acciona, S.A); Germany’s Ed. Züblin (22%); Australia’s Downer and Co (22%); and Hong Kong’s Paul Y (12%). Constructing engineers were Schlaich Bergermann & Partner
