Abstract: Perform3D is a structural-engineering software useful for the performance assessment of structural systems. State-of-the-art constitutive-modeling capabilities enable characterization of material nonlinearity, including strength and stiffness degradation during component-level hysteresis. Analysis capabilities also extend to geometric nonlinearity and effects associated with P-Delta behavior. Advanced modeling tools enable a sophisticated simulation of structural behavior. Components may be grouped according to type, location, and limit state before evaluation proceeds in terms of strength or deformation-based demand-capacity ratio. The dynamic display of D-C usage is available through color-coordinated time-history animations.

Computer Analysis and Design of Earthquake Resistant Structures: A Handbook
Author(s)/Editor(s): D. E. Beskos (editor), S. A. Anagnostopoulos (editor) | Size: 15 MB| Format:PDF| Quality:Scanner| Publisher: WIT Press| Year: 1996 | ISBN: 1853123749
This handbook represents an edited collection of 18 chapters on the analysis and design of earthquake-resistant structures by numerical methods, especially software-based methods. Written by well known specialists in the field, they include tutorial as well as state-of-the-art material. The book thus may also be used as a reference source for additional information.
The Handbook is unique in its kind as it combines in a single volume self-contained chapters on a great variety of structures not found elsewhere in one book, with a wealth of background material covering the required related subjects. No other book on earthquake engineering, old or recent, combines tutorial and state-of-the-art material of this subject from the modern viewpoint of computerized methodologies.
More specifically, the book covers numerical methods in earthquake engineering, stochastic analysis methods, engineering seismology, strong ground motion and site effects, seismic hazard analysis and modeling, buildings, reinforced concrete structures, steel structures, masonry structures, bridges, dams, storage tanks and silos, offshore structures, underground and lifeline structures, seismic isolation and control, and repair and strengthening.

A detailed view on the effects of seismic activity on tank structures
As the use of above-ground and underground storage tanks (ASTs and USTs) continues to grow―with approximately 545,000 in the USA alone―the greatest threat to ASTs and USTs is earthquakes, causing the contamination of groundwater, a vital source of drinking water throughout the world. These tanks suffer a great deal of strain during an earthquake, as a complicated pattern of stress affects them, such that poorly designed tanks have leaked, buckled, or even collapsed during seismic events. Furthermore, in oil and gas industrial plants, the risk of damage is even more critical due to the effects of explosion, collapse, and air or soil contamination by chemical fluid spillages.
Seismic Design and Analysis of Tanks provides the first in-depth discussion of the principles and applications of shell structure design and earthquake engineering analyses focused on tank structures, and it explains how these methodologies can help prevent the destruction of ASTs and USTs during earthquakes. Providing a thorough examination of the design, analysis, and performance of steel, reinforced concrete, and precast tanks, this book takes a look at tanks that are above-ground, underground, or elevated, anchored and unanchored, and rigid or flexible, and evaluates the efficacy of each method during times of seismic shaking―and it does so without getting bogged down in impenetrable mathematics and theory.
Seismic Design and Analysis of Tanks readers will also find:
A global approach to the best analytical and practical solutions available in each region:
discussion of the latest US codes and standards from the American Society of Civil Engineers (ACSE 7), the American Concrete Institute (ACI 350,3, 371.R), the American Water Works Association (AWWA D100, D110, D115), and the American Petroleum Institute (API 650)
an overview of the European codes and standards, including Eurocode 8-4 and CEN-EN 14015
Hundreds of step-by-step equations, accompanied by illustrations
Photographs illustrating real-world damage to tanks caused by seismic events
Perfect for practising structural engineers, geotechnical engineers, civil engineers, and engineers of all kinds who are responsible for the design, analysis, and performance of tanks and their foundations―as well as students studying engineering―Seismic Design and Analysis of Tanks is a landmark text, the first work of its kind to deal with the seismic engineering performance of all types of storage tanks.

What is BS 8102 – Code of practice for below ground structures about?
BS 8102 focuses on below ground structures. BS 8102 provides best industrial guidance for design of below ground structures to prevent contamination.
BS 8102 gives recommendations and provides guidance on methods of dealing with and preventing the entry of water from external sources into structures that are partly or wholly below ground.
It covers the use of:
Waterproofing barrier materials applied to the structure
Structurally integral watertight construction
Drained cavity construction
Who is BS 8102 - Code of practice for below ground structures for?
BS 8102 on windscreen repair is useful for:
Manufacturers of waterproofing and drainage systems
Design engineers
Architects
Product specifiers
Geotechnical engineers and site investigators
Contractors
Site engineers
Building control – local authority and private
Why should you use BS 8102 - Code of practice for below ground structures?
Strategies for dealing with all external sources of groundwater, surface/flood water, soil gases and contaminants should be determined from the very earliest stages of the planning and design processes for any project involving below ground structures.
BS 8102 provides guidance on the drainage outside the structure and recognizes the risk of water entering a structure through openings. BS 8102 covers structural design, overall weatherproofing design, waterproofing design and construction processes sequencing, and buildability of the structure BS 8102 provides methods for evaluation of groundwater conditions and consideration of harmful ground gases, risk assessment and how to manage these risks in below ground structures. This will ensure development of a robust design for protecting a structure from entry of water from external sources.
BS 8102 contributes to UN Sustainable Development Goal 9 on industry, innovation and infrastructure and Goal 11 on sustainable cities and communities.

The long-term performance of concrete repair intended to address corrosion of embedded reinforcing steel is influenced by the depth of repair and the condition of the substrate concrete surrounding the repair area. The extent of concrete removal should be adjusted in accordance with the degree and nature of distress affecting the member or structure, while taking into account the concrete condition, the structural design, and the applied loads.
