Bs 6399 Part 3 Pdf Free Download

Part 2 of British Standard BS 6399 is wrongly perceived to give larger loads than the CP3 Code of Practice. The one change between the two Codes that tends to increase structural loads is the modification of the 'division by parts' rule, which is Clause 5.5.2 of BS3 and Clause 2.2.3.2 of Part 2. This paper discusses the implementations of the rule for both Codes and their wider implications. For CP3, the intent of the rule as drafted, the rule as implemented, and the consequences for structural loads are considered. The implementation became out of date as new knowledge was obtained about wind pressures on the front, side, and back faces of buildings. In view of the overwhelming evidence obtained, it was decided to drop the rule entirely from the original draft of Part 2, but the rule was reinstated in a modified form in response to public comments. The consequences of the modified rule for structural design are discussed.
I missed lots of awesome Lego during my dark ages - for me, that was late 80s to early 2000s. Once I got back into Lego as an AFOL with kids, there have been certain missed sets that I just had to get. Some to keep, some just to build, play with, and then sell on to others. One of the latter category was the Airport Shuttle monorail set. Due to the extremely high price, I had no intentions of keeping the set, but I wanted to try it and show it to my kids. I set up a Bricklink and ebay alert and waited. Finally, one came along at a price I was willing to pay.
The box is large - easily as big as the largest modern sets like the Technic flagships. The front has a decent photo of the set, although it's so large of a layout that even Lego couldn't get it all to fit the box without an inset.
Like other old sets, this box has a flip-up panel on the front so you can see inside. I'm sure originally the pieces were nicely displayed under the plastic, but the molded inner part has been lost. Now the pieces just are a jumbled mess.
The inside of the lid has a nice array of photos showing what the set can do. There's some action shots of the figs using the train and stations, plus a trio of images showing how the monorail can be controlled with the switch tracks. I think the best one though is the top photo with the boy. Having a real child playing with the set shows just how large and awesome this layout is.
Now this is what's missing from modern Lego. Suggestions to make your own mods! New station designs, even new train variations! My favorite by far is the safari monorail in the top right. A great open car for seeing the animals, a decent brick-built elephant, and a nice tour guide in the front.
The front cover of the manual (just one manual!) has the same image as the box, plus it shows you the minifigs in a group so you can assemble them correctly. They're easier than modern figs though, since they all have the same head! You can't really see from this photo, but this is a THIN manual. There's only 20 some pages to it. Considering you build two large train stations, a monorail train, and the track layout, things must move fast once you open this book...
Wow, this is so different from modern Lego manuals. Here, in just two pages, nearly a whole train car is built! 5 steps add several dozen parts, rather than the 10 or so you'd add in 5 steps today. They even assume kids have brains - check out the cover for the motor on the right-hand page. They didn't tell you explicitly to put the 1x4 tile and 1x2 grills on the back of the cover! They thought a kid could figure out to do both sides the same!
This set comes with NINE figs! You get an engineer to run the monorail, a white-gloved steward to take care of the passengers on their long train journey (what? Seems so unnecessary!), a dad for the travelling family, a pilot headed to the airport, mom with her red-necklaced torso, a red-headed daughter, two sons with plane and truck shirts, and finally a cook for the hot-dog stand. How many hot-dog stands have chefs with chef hat and formal attire though? He should be in greasy casual clothes. And being from 1990, they all have the same head.
Here's how the monorail itself works. There are special train bases. One end has a thicker spot with a pin hole for the wheels, and the other end has a tab that will connect to the motor. There's no easy way to make a longer train than car-motor-car. You'd have to custom-build a coupling system to extend it. The wheels themselves are fairly complex. The pin lets the bogey rotate, and the pin is mounted on a pivoting section to let it tilt forwards and back to handle the ramps. There's a slot through the underside of the bogey that straddles the ridge in the tracks, keeping the train on the track.
The red 9V battery box. It's only ever been in two sets (in red; this 9V box has come in black, red, white, and yellow over the years) , but I sorta wish it would come back in the PowerFunctions system. It's so nice and compact. There's a 2x6 section of powered studs on top for attaching multiple things if you wanted, and the raised grey studs at the left end are the power switch. They latch down to turn the power on.
Here's just how small the battery box is. A single 9V battery just fits inside. Granted, a modern battery box with 6 AA or AAA batteries will last longer, but they're so much bigger. I wish Lego would come out with a rechargeable box this size or smaller. You could get a lot of power in that space using modern lithium batteries.
This is how much you build on just the first 2 page spread of the manual. The front of the train has the battery box, two passenger seats, and a cockpit for the driver. A little bit of SNOT at the front gives headlights.
On the bottom, the motor has a metal gear. That meshes with the teeth of the track, letting the monorail handle hills with ease. The points sticking out to each side are a switch. In the middle (as shown here), the motor is off. Pushing the switch in on one side makes the motor go, and pushing in the other side makes it go the other direction. This lets you set switches on the track itself to control the train, as we'll see later in this review.
The second car of the monorail builds very much like the first, but with extra seating space since there's no battery box taking up half the car. You get another driver's section (since the monorail can run either direction) and three seats. I guess the space in the back (towards the motor) is luggage storage, since it's hard to access.
The Airport Shuttle comes with two large, 32x32 baseplates. The green one appeared for the first time in this set, but showed up 4 times over the years later. The grey version ONLY ever appeared in this set, making it run $15-$20 for used ones.
The first station of the shuttle begins like this. Two smaller green baseplates are added onto the back of the large one to extend the space. They're only attached though by the 2x3 bricks on the outside edges - just 2 studs of each small plate ever attach. That makes it weak and hard to move the station later. Lego really should have put a few plates across the edges here to strengthen the ground.
Just a few steps and the station is nearly done. There's a long platform for the boarding the monorail, steps up to it, a couple storage lockers on the left, a phone booth near the road, and even little ticket scanners at each staircase. Lego did a great job here keeping things simple but very playable. The white curved panels making the base of the awning are pretty cool, and very rare. They've been made in other sets in clear and trans-light blue, but only here in white. So yeah, they're $5 each to replace. And that's not even counting the stickers!
And the station is done. The awning is complete with a nice airport sticker on top (although annoyingly, that sticker is across 3 1x4 bricks), flowers have been added, and the track is in place. You'd think the track would strengthen the extra baseplates that it's on, but you'd be wrong. The track keeps popping off, because it's only attached with a couple studs. (Actually, I'm wrong about that. The center of the switch track is a large attachment point, but I never got it properly attached when I first built the set. When I rebuilt it later, I got it on right and it's much stronger.)
Speaking of the track, let's take a quick look at the Lego monorail track. This is the short straight piece. There are also long straights, short and long curves, left and right switches (aka points), the control switch, and ramp top and bottom parts. All have this toothed rail running down the middle to guide the train. There's studs at the ends on the sides - the track pieces are connencted by adding 1x4 plates or tiles to those studs. On the underside, there are some stud connections. They stick down from the track so that the edges of the track don't hit other studs. However, the small section of connection makes it a weak connection.
As a minifig arrives at the station, this is what they'd see. Nice little signs in the center directing them, a town map on the awning, a phone booth, and some random seats near the phone. Oh, and completely exposed tracks with no guard rails of any kind to protect the kiddies from running out onto the tracks and getting hit. Hey, it was the early 90s and lawyers hadn't sued everyone yet.
On the awning is this nice map. The train track is actually shown as the double loop layout with two stations that the set uses. It even shows the driveway at each station correctly, with the little island splitting the roadway. Even the green vs grey baseplates are correct! The rest of the town and road, though, are not included.
This is a great little surprise Easter Egg in the set. Those "flight numbers" are actually Lego train set numbers from the 1980s, spanning the 4.5V and 12V era. 7725 is the Electric Passenger Train, 7755 is the Diesel Heavy Shunting Locomotive, 7720 is the Diesel Freight set, and 7715 is the Push-Along Passenger Train. The last two numbers (7719 and 7721) are not trains though. They're Bionicle and Exo-Force sets from the mid-2000s. I wonder if those numbers were used internally at Lego for trains or something? Or train sets that were never released?
