Beam theories are exploited worldwide to analyze civil, mechanical, automotive, and aerospace structures. Many beam approaches have been proposed during the last centuries by eminent scientists such as Euler, Bernoulli, Navier, Timoshenko, Vlasov, etc. Most of these models are problem dependent: they provide reliable results for a given problem, for instance a given section and cannot be applied to a different one.
Beam Structures: Classical and Advanced Theories proposes a new original unified approach to beam theory that includes practically all classical and advanced models for beams and which has become established and recognised globally as the most important contribution to the field in the last quarter of a century.
The Carrera Unified Formulation (CUF) has hierarchical properties, that is, the error can be reduced by increasing the number of the unknown variables. This formulation is extremely suitable for computer implementations and can deal with most typical engineering challenges. It overcomes the problem of classical formulae that require different formulas for tension, bending, shear and torsion; it can be applied to any beam geometries and loading conditions, reaching a high level of accuracy with low computational cost, and can tackle problems that in most cases are solved by employing plate/shell and 3D formulations.

A comprehensive treatment of current fastening technology using inserts (anchor channels, headed stud), anchors (metal expansion anchor, undercut anchor, bonded anchor, concrete screw and plastic anchor) as well as power actuated fasteners in concrete. It describes in detail the fastening elements as well as their effects and load-bearing capacities in cracked and non-cracked concrete. It further focuses on corrosion behaviour, fire resistance and characteristics with earthquakes and shocks. It finishes off with the design of fastenings according to the European Technical Approval Guideline (ETAG 001), the Final Draft of the CEN Technical Specification 'Design of fastenings for use in concrete' and the American Standards ACI 318-05, Appendix D and ACI 349-01, Appendix B.

Design process of a reinforced concrete shell element involves two major steps: analysis
and design. Development of the computerized linear elastic analysis techniques, such as
the finite element method, has essentially solved the first part of the problem. Design, on
the other hand, is not as easy to handle since the number of unknowns is larger than the
number of available equations of statics. Due to this fact, many design methods have been
developed by various researchers. This thesis attempts to compare the more important
existing methods of analysis of orthogonally reinforced concrete shell elements with each
other. A Windows-based computer program is written in Visual Basic to implement these
methods and to facilitate the analysis. First, the selected results of the methods are
compared with available experimental data. Since the amount of experimental results is
not adequate for a definitive compariso~ a parametric study is carried out. The modified
compression field theory is used as a reference in the parametric study. The effects of
loading, reinforcement ratio, and concrete strength on the strength of a total of 720 panels
investigated. The research showed that under highly unsymmetrical loading conditions,
and in the cases where the reinforcement ratio in one orthogonal direction is quite different
from the one in the other direction (highly orthotropic ), the accuracy of the existing
methods of analysis significantly decreases. Change in concrete strength played an
important role only in the methods which used simple models for concrete behaviour.
Based on the present investigation, suitable methods are identified for different load
cases, and recommendations for future work are made.

Two fundamental flow phenomena, the separation bubble (SB) and conical vortex~
over the roof (flat and rectangular) of the Texas Tech test building are studied in terms of
flow characteristics and pressure-generating mechanisms. Major fmdings contribute to
understanding the mechanisms of pressure generation and the roles of turbulence and
other properties of the incident wind in loading effects.
Much of the debate on wind-tunnel simulation priority in the wind engineering
community has failed to distinguish the different effects the incident wind has on two
types of quantities: single events, e.g., minimum (peak) pressures, and statistics~ such as
the mean and the rms pressures. The turbulence intensities, reflecting the gust structure
and the directional fluctuations of the free-stream wind, might bear significant influences
collectively on the pressure statistics. It is the intensity of individual longitudinal gusts
(as well as the incident wind angles) that decides the data-run-wise peak-pressure
coefficients on the roof corner~ while the peak-pressure coefficients associated with the
SB are governed by the lateral directional fluctuation in the incident wind. Proper
simulation of the incident wind profile (boundary layer type) is probably the most
important single input in the wind- structure interaction process.

I have a suggestion for new forum sub-section "Mobile Civil Software" and sub-forums "Android OS" , "iOS" and "Windows Mobile" etc.
There is lot of programs for smartphones and tablets, but there isn't some kind of a Index for this programs, also there reviews are not very reliable.
