For studying the overall instability of members of steel structures, there are several methods in which overall buckling and geometrical imperfection effects considered in analysis. In first section, these methods are compared and ability of software to apply these methods is studied. Buckling loads determined from theoretical methods and software is compared for 2D one bay, one and two stories steel frames. To consider actual condition, buckling loads of three steel frames have various dimensions are calculated and compared. Also, uncertainties that exist in loading and modeling of structures such as geometrical imperfection, yield stress, and modulus of elasticity in buckling load of 2D framed steel structures have been studied. By performing these uncertainties to each reliability analysis procedures (first-order, second-order, and simulation methods of reliability), one index of reliability from each procedure is determined. These values are studied and compared.

The open games, which commence 1 e4 e5, are some of the most exciting and
important in chess. In this, the first of a four-volume series covering all of the
major openings, former World Champion Anatoly Karpov presents a survey of
the Ruy Lopez, the Russian (or Petroff), the Scotch, the Italian (or Giuoco
Piano) and the Four Knights. Complete games from recent Grandmaster play
are analysed in depth, so that the reader sees the logical connection of the
opening to the middlegame (and beyond).
This is not only an excellent book for players wishing to improve their
understanding of the opening; it is also highly entertaining, and all players will
find much to enjoy.
Anatoly Karpov was World Champion from 1975 to 1985, during which time he
dominated the chess world, becoming the most successful tournament player
in history. His recent epic struggles with Gary Kasparov have proved that he is
the only player in the world capable of successfully challenging Kasparov for
the World Championship.
دفاع برلین
Since Vladimir Kramnik became world champion in 2000 due at least in part to the Berlin Defence, this opening setup has become extremely popular. Not only did it turn out to be very safe, it also showed that often Black can even take the full point is White does not play accurately. Leonid Kritz has annotated for ChessBase Magazine a lot of top games with this opening. In addition, the German grandmaster has tried out his special setup against strong opposition and is convinced by it. In his videos
he demonstrates:
- a program for Back after 4.d3
- the main variation 4.0-0 Nxe4 5.d4 Nd6 6.Bxc6 dxc6 7.dxe5 Nf5 8.Qxd8+ Kxd8
9.Nc3 and then Kritz’ recommended setup 9...Ke8 10.h3 Be7
- deviations 6.dxe5, 6.Bg5 and 6.Ba4
- the side variation 5.Re1
