This document provides guidelines for ductile detailing of reinforced concrete structures in seismic zones. It specifies that ductile detailing is required for structures in Seismic Zones IV and V, as well as some structures in Zone III. Concrete must have a minimum compressive strength of 20 MPa and steel reinforcement grade of Fe 415 or less. Flexural members must have a width-to-depth ratio over 0.3, width over 200mm, and depth less than 1/4 of clear span. Longitudinal reinforcement requires a minimum of two bars at top and bottom with minimum and maximum steel ratios specified. Joints and splices must be confined by hoops or laps exceeding development lengths to ensure ductility. Web reinforcement of closed
This document provides guidance on designing portal frames according to Eurocode standards. It discusses the importance of accounting for second order effects in portal frame analysis and design.

There are two main types of cofferdams: single wall and double wall. A single wall cofferdam uses a single line of sheet piles and is suitable for small, shallow work areas up to 25 meters deep. A double wall cofferdam uses two lines of sheet piles tied together with the space between filled with sand or clay. It is used for larger, deeper work areas. Both types are constructed by driving guide piles, installing horizontal beams, and securing sheet piles to create the barrier to pump water out of the enclosed area.
Vectorbloc presentation online Feb 2015Julian Bowron
The document describes Precision HSS Connection System, a standardized modular building system called Vectorbloc. Vectorbloc aims to address challenges with modular construction by providing a precision structural connection system that allows modular building blocks from multiple suppliers to efficiently assemble into complete buildings of various sizes, from low-rise to high-rise. The key components of Vectorbloc include precision structural connectors called Vectorblocs, an extendable gasket system, a hoisting system, and a surveying and leveling system, which work together to enable rapid, standardized modular assembly with tight tolerances. Vectorbloc hopes to make modular construction more efficient and cost-effective for constructing apartment buildings, hotels, hospitals and other building types.
Rajkiya Engineering College, Bijnor presented information on bridge engineering. Bridges are key infrastructure that allow crossing of obstacles like rivers and canals. A bridge consists of substructure elements like foundations, piers, and abutments, and superstructure elements like the deck. Bridges are classified by span length, material used, and the type of superstructure. Bridges improve transportation, emergency response times, and reduce traffic congestion. Selection of a bridge type depends on site conditions, traffic needs, structural requirements, and material availability.
Here is the table explaining the types of materials available for formwork:
Material | Suitability | Advantages | Disadvantages | Cost
-|-|-|-|-
Timber | Suitable for all types of formwork including beams, columns, slabs and foundations. Commonly used material. | Readily available. Easy to work with using basic carpentry tools. Can be reused multiple times if properly maintained. | Requires more maintenance between uses. Subject to damage. Absorbs water reducing quality of concrete surface. More combustible. | Low cost.
Plywood | Suitable for slab formwork and walls. | Strong and durable. Provides smooth concrete finish. Water resistant. | Heavier than timber. Requires proper support

Tunnel form is a formwork system that allows to cast walls and slabs in one operation on a daily cycle. It combines the speed, quality and accuracy with the flexibility and economy of in-situ construction. Construction durations are reduced significantly by this rapid system when compared to conventional methods. The system creates efficient load-bearing structures which are known as the most earthquake resistant structures. Rohan Builders has adopted the technique at its Rohan Abhilasha project in Wagholi in Pune.
This document discusses different methods for manufacturing precast concrete components, including factory prefabrication, site precasting, and semi-mechanized and fully-mechanized production. It describes the main processes like forming, reinforcement, pouring, curing, and demolding, as well as auxiliary processes. Transportation of the precast elements and their erection are also covered.

What is Stone Crete Plaster / Exposed Aggregate Plaster?
Stone Crete Plaster is composed of a mix of elements: cement, coarse aggregate (usually crushed stone), fine marble powder and water. You can change the look of the finished plaster by making changes in the elements using white cement instead of gray cement, for example, or using crushed colour glass in place of crushed stone. These choices can change the look of exposed aggregate concrete dramatically.
Special decorative aggregates frequently used for exposed Stone Crete Plaster and include a variety of decorative stones in many different colours. While Stone Crete Plaster finishers usually hide the aggregate with a smooth layer of cement paste, you can create aesthetically appealing looks by exposing the aggregate. Stone Crete Plaster is a 12 to 15 mm thick granular effect decorative texture.

This document discusses different techniques for connecting steel structures, including riveted, bolted, and welded connections. Riveted connections were commonly used in the past but have become less popular. Bolted connections are now more common as they are easier to install and do not require skilled labor. Welded connections provide a strong bond but require more precision. The document explores the advantages and disadvantages of each connection type and describes processes like electric arc welding and oxy-acetylene welding.
Different types of damages that have been observed in masonry buildings durin...Nitin Kumar
The document summarizes different types of damages observed in masonry buildings during past earthquakes outside and inside India. For earthquakes outside India, it describes damages like through diagonal cracks or X-shaped cracks on walls, horizontal cracks on walls and bearing brick columns, severe damage to stair parts, and damage to non-structural components like parapets and corridor fences. It also discusses damages caused by structural irregularities. For earthquakes in India, it lists failure patterns of masonry structures under categories such as out-of-plane flexural failure, in-plane shear failure, separation of walls at junctions, corner separations, failure of masonry piers, and collapse of wythes.
Wall ties are used to tie together the two leaves of a cavity wall, making the wall stronger and able to support more load. The ties must be placed correctly by the bricklayer in accordance with building regulations, with spacing no more than 150mm from openings and 750mm horizontally and 450mm vertically. Proper placement involves pressing ties fully into each wall leaf with any drip pointing downwards in the center of the cavity. Special wall ties are needed when cavity insulation is used to support the insulation at intervals.

Gli spettacoli e gli eventi realizzati in spazi urbani non destinati per loro natura a tale fine come piazze, stadi, impianti sportivi e perfino stazioni delle linee metropolitane e ferroviarie, necessitano di allestimenti temporanei che implicano, sotto il profilo strutturale, attività progettuali ed esecutive di elevata complessità e rischiosità, anche tenuto
conto dei ristrettissimi tempi di realizzazione.
Ne sono riprova i purtroppo non infrequenti fatti di cronaca con crolli e sacrificio di vite umane in infortuni mortali durante il montaggio o lo smontaggio di palchi e attrezzature temporanee.
Il seminario - tenuto conto dell’assenza nei normali curricula professionali di specifici corsi - intende illustrare le problematiche connesse con opere che si connotano, a tutti gli effetti, di alta ingegneria strutturale, nonché i connessi aspetti procedimentali.
