Moreover, the natural boundary conditions are not satisfied completely because they are not enforced a priori [International Journal of Solids and Structures 2001 38 6525 58, Journal of Computational Structural Engineering 2001 1 1):49 57, Journal of Structural Engineering ASCE 2002 128(2):249–57, Computers and Structures 2002 80(2002 8054].
All structures are modeled and analyzed in this paper using ETABS and Sap2000 (Computers and Structures, Inc 2003, 2007, 2011[a, b]).
SAP2000 Computers and Structures, Inc. (2005) was used to develop detailed nonlinear 3D FE as well as improved BS models, whereas DRAIN3DX Prakash et al. (1994) was employed to develop the improved BS models only.

Natural frequencies and corresponding mode shapes of the 55- and 65-storey buildings are obtained by the proposed method and compared with SAP 2000 computer analysis results (SAP 2000 Advanced 12.0.0, Computers and Structures, Berkeley, CA, USA) (see Tables 2, 3 and Figs. 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22).
The approach can be regarded as an extension of that proposed by Au [Au SK. Reliability-based design sensitivity by efficient simulation. Computers and Structures 2005 83(14):1048–61], but it proposes a better framework in estimating the failure probability function.
Currently, because of the efficiency of the macroscopic models, existing structural analysis platforms such as Perform 3D (Computer and Structures Inc. 2006), OpenSEES (PEER 2001), and DRAIN-2DX (Prakash et al. 1993) use macroscopic models for the nonlinear analysis of wall systems.
Advances in information technology also affect the use of computers and the structure of the organization driving firms towards decentralization.
Computer-aided and structure-based drug design have guided the addition of solubilizing substituents to the diaryltriazine scaffold.
Given the high degree of conservation of Thr201 and Tyr204 among different species, along with computer modelling and structure activity relationship studies of BP inhibitors [16], [17], [35], it was postulated that these residues play a pivotal role in allylic substrate binding.
In this review, we describe some of these methods, including analyses of X-ray crystallographic data and structures, computer simulations, NMR data, and covariation among protein sequences, and indicate the critical insights that such methods provide into protein function.
