The proposed cast-in-situ unreinforced concrete structures is a multi-cells storm drainage Culvert along road (Typical). The structure is designed as moment and shear resisting frames consisting of unreinforced precast concrete arches roof and unreinforced conrete walls on continuous unreinforced base slab serving as mat foundation supported by node springs.
The whole structure is modelled as series of elements, analyzed and designed by STAAD Pro structural program in accordance with ACI Code, using Ultimate Strength Design (USD) method.
All applicable loads are in accordance with MOT and AASHTO requirements and applied on structure such as dead loads, selfweight, soil pressure and surcharge on exterior walls etc. Wheel load pressure per MOT Design Trucks & Lane Loads such as; standard lane- load per lane 20 kN/m UDL, 150 kN for moment and 220 kN concentrated loads spread over lane width; 3 axle 600 kN (61.2T) truck per lane, and 320 kN (32.62T) hypothetical single axle load per lane are applied on structure in different loading pattern/cases similar to a moving loads.
All these loads are applied systematically in various critical load combinations with corresponding load factor multipliers, as required by AASHTO.
Please refer to design load calculations, Wheel Loads Summary Table and diagrams.
Arch culverts are designed to safely withstand the vertical and lateral loads due to traffic and earth and comply with minimum factors of safety and 100 kPa recommended net allowable bearing capacity as per RC manual.
A beam or column that relies on adjacent structural members for support is braced in a lean-on system. Structural members that are tied or linked together such that buckling of the member would require adjacent members to buckle with the same lateral displacement characterize lean-on systems.
The eight bolt stiffened (8ES) EEP connection is one of the prequalified moment connections in the AISC 358 standard for special moment frames (SMFs) in seismic regions. In this connection, a stiffener plate is welded between the end plate and the beam flanges to strengthen the extended portion of the end plate.
Flush Wall Pilaster. This program provides design and analysis of columns contained entirely within the thickness of a masonry wall. The column may be subjected to a combination of eccentric vertical loads and lateral loads due to seismic or wind forces.
This book is all original and specifically designed to get you working with Revit Architecture or its other applications as knowledgeably as possible. It is comprehensive and aims to give you a deeper understanding and a better learning experience.
This book is specially design for Architecture and Civil students according to their need.This content helps students to understand BIM and its workflow, to design buildings in better way.
It is useful for students who want to learn Revit Architecture on any version of Revit like 2016, 2017, 2018, 2019, 2020, 2021. This book is created on Revit 2021 with its all new features.
No previous knowledge of software required to learn Revit by this book.After completing this book, you will be able to create your own projects on Revit with all detailings.
he objective of this book is to provide you with extensive knowledge of AutoCAD, whether you are taking an instructor-led course or learning on your own. AutoCAD 2021 From Zero to Hero is an ideal reference guide, unlike tutorial-oriented books where specific information is hard to found. This book helps you become an AutoCAD expert and has been fully updated to cover all of the AutoCAD?s new capabilities. This indispensable resource teaches AutoCAD essentials using concise explanations, focused examples, step-by-step instructions, and hands-on projects.
