Design Aspects For Terrorist Resistant Buildings

ABSTRACT:

All western democracies are now acutely aware of the apocalyptic consequences of a well-orchestrated attack on high-profile government facilities and other related targets. Many of these buildings are historical, ornate, listed and constructed using traditional techniques. Many of the modern retrofitted reinforcement techniques used to protect these structures against terrorist attacks are unsightly, intrusive or inappropriate. However, security specialists are well aware that while there might be little that can be done to defend a building against an aircraft attack, much can be done to defeat the more traditional car bomb and bullet. The methods available to the structural engineer to strengthen existing structures and provide resistance to the effects of a blast attacks are discussed in this paper.

1. INTRODUCTION:

The design of civilian or commercial buildings to withstand the effects of a terrorist blast is unlike the design of military installations or the design of embassy buildings. The objectives of the “Structural Engineering Guidelines” for the Design of New Embassy Buildings are to prevent heavy damage to components and structural collapse. Adherence to the provisions of the guidelines will minimize injuries and loss of life and facilitate the evacuation and rescue of survivors. The blast-protection objective of any commercial or public building must be similar to those of embassy structures, that is, to prevent structural collapse, to save lives, and to evacuate victims.

Architectural and structural features play a significant role in determining how the building will respond to the blast loading. These features can include adjacent or underground parking, atriums, transfer girders, slab configurations, and structural-frame systems. The keep-out distance is vital in the design of blast resistant structures since it is the key parameter that determines the blast overpressures that load the building and its structural elements. The degree of fenestration is another key parameter as it determines the pressures that enter the structure. The smaller the door and window openings the Embassies and military structures occupy secure sites with substantial keep-out distances better protected the occupants are within the structure. Following these key parameters,

Different Failures in RCC Buildings

By
Priyanka Gupta

1.0 Introduction

In small residential buildings the quality of construction is seldom questionable. The reason varies from poor building material quality to lack of knowledge of good construction practices. Most of the times, engineers are ignored by individual house owners and masons are given sole responsibility of both design and construction. Almost all structural engineers practicing in India will agree that 99% of the failures of structures in India are not due to design failure.

Explaining the different aspect of construction that a normal home builder, engineer or contractor needs to remember.

Study Of Planning of Public Building

INTRODUCTION
Urban India today, faces serious challenges of growth and its management. Across geographies, the issues of urbanization manifest in the form of overcrowding, congestion, insufficient infrastructure, inadequate service provisioning mainly in terms of drinking water, sanitation, energy, transport, solid waste management, environmental degradation, and pollution, etc. These, along with the poor management of rapid growth, affect the socioeconomic development of the country.

So by using newly and broadly available technique in construction infrastructure town planning engineer or planner can establish well developed buildings. Which are good in aesthetic safety proof and any disaster free. Public buildings are old in construction such as famous auditorium markets schools colleges are good in construction but sometimes safety issues are creates for such kind of view it is necessary to study and built safer public building. Again with safety there are lot of energy systems are used in public buildings such as lights fuels gas water etc. Due to urbanization these things are very much required to human beings but these things are non renewable or pollution making things so it is need to use concept of green buildings used in the public buildings.

LITERATURE REVIEW
Plan of the building is the assembling and grouping and arranging its component parts in systematic manner and in proper order. So as to form a meaningful wholesome and homogeneous body with a comprehensive look out to meet its functional purpose.

Parking Patterns In Order To Menace Traffic Chaos

Abstract
“License to drive is not a license to kill”. The unscrupulous growing population has created many problems in country like India. One of the challenging ones being car parking which we confront almost every day. Besides the problem of space for cars moving on the road, greater is the problem of space for a parked vehicle considering that private vehicles remain parked for most of their time. While residential projects still escape with designated parking, the real problem lies with commercial spaces many a time which is overcome by taking extra open spaces to park.

Problems of using High Grade Steel in Constructions

Presented by:
1) Prof.M.V.Kuriakose B.Tech(Ed), M.I.E. (Retd.Principal, Govt.Polytechnic, Perinthalmanna)
2) Mr.Jismon Issac B.E (Mech) A.I.E, MBA

[Prof.M.V .Kuriakose is having around 35 years of expertise in Structural Engineering and Designing. He is an active member of Lensfed.]

[Mr.Jismon Issac has 13 years of experience in the manufacturing & Quality testing of Construction Steel bars especially High grade TMT steel bars]

Now days some contractors report a tendency among few design Engineers that they specify grade Fe-500 or higher steel in residential buildings, citing its high strength. If they design buildings considering the use of Fe 500 steel in construction, it could help reduce the volume of steel used and reduce the column size.

The rosy part aside, Fe 500 grade steel could pose quite a few site specific issues during construction, especially for small builders. Considering the reported failures and problems with grade Fe-500 or higher, it is advisable to use Fe 415 in residential and commercial buildings and Fe500 could be used only when the entire design is made according to that grade. This is explained below;
