The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.
The Manual explains the concept of transferring the load from the super structure up to the soil throughout Piles, which has a capacity of (End bearing, and Skin friction). It illustrates the steps needed to produce a full and safe foundation for your Super Structure.

Designing a Concrete Beam Using the New AS3600:2018 - Webinar Slides - ClearC...ClearCalcs
The 2018 revision of the AS3600 Concrete standard includes major revisions for areas including phi factors, shear, deflection, rectangular stress block, and shrinkage/creep.
In this webinar, ClearCalcs lead engineering developer Brooks Smith discusses some of these key changes, and runs through the design process for a concrete beam design before demonstrating a few worked examples using AS3600:2018 in the newly released rectangular concrete beam calculator on ClearCalcs.com.

Bridge Engineering and Extreme Events: Wind effects on bridge decks Julianne Crawford
Following a series of catastrophic bridge failures, the adverse effects of wind loading on bridges has become a widely discussed topic in the realm of bridge design and research. Currently however, the majority of research focuses on the contribution of wind in long span bridge design. This is primarily because long span bridges have a greater inherent tendency to become aerodynamically unstable. Nonetheless, wind can also contribute to the shear and moment of short span bridges, thereby influencing the limit state of various components in these short span bridge systems. To narrow this scope, the following presentation focuses specifically on the contributions of wind to the shear and moment of slab and girder bridge decks. These contributions are quantified by a model that calculates the shear and moment due to wind loads for a number of variable parameters including angle of impact, bridge height, span length, and deck thickness. Ultimately, it is found that angle of attack has the greatest impact on moment, while span length has the greatest impact on shear about center span.
Collapse propagation in bridge structures. A semi-analytical modelDCEE2017
Michele Brun.
We consider the advance of a transition flexural wave through a beam-like periodically supported slender structure. The
collapse of a bridge structure is modeled as a steady-state propagation of a transition wave within a slender structure. The problem is
governed by fourth-order partial differential equations and both propagating and evanescent waves are included in the general solution. It is
shown that the problem can be expressed within a class of functional equations of the Wiener-Hopf type . Three different propagation
regimes are found: subsonic, intersonic and supersonic and it is shown that propagation is restricted to the intersonic regime where part of the
energy is released to the damaged structure.
Applications to the study of the collapse of the San Saba bridge in Texas shows the validity of the model.
Shear, bond bearing,camber & deflection in prestressed concreteMAHFUZUR RAHMAN
This Presentation was presented as a partial fulfillment of Prestressed Concrete Design Lab Course. Behavior & Design of Prestress on above topic is shortly discussed on the presentation. The part "Shear & Shear Design in Prestressed" Concrete was prepared by me. Other topics were prepared by other members of my group. Thanks to all my teachers & friends who helped us in different stages during preparation of the total presentation.
