The loads Acting on staircase.

Distribution of Loads and its Effect on Staircase Stair slabs are usually designed to resist gravity loads, comprising of dead loads and live loads as described below: 
1) Dead Load: The components of the dead load to be considered are:
a) Self-weight of stair slab (tread/tread-riser slab/waist slab)
b) Self-weight of ...

 LIVE LOADS:-
IS 875 parts II specifies the load to be considered as UDL of intensity 5KN/m2 for public 
buildings and 3kN/m2 for residential building where the specified floor do not exceed 2kN/m2 and the staircases are should not liable for overcrowding.

 DEAD LOADS:-
Self-weight of stair slab which includes the waist slab, tread-rise,etc. Self-weight of finishes (0.5 to 1 kN/m?)
Types of stairs                                                                                            
  • Straight flight stairs.
  • Dog legged stairs.
  • Open newel stairs.
  • Quarter turn stairs.
  • Bifurcated stairs.
  • Geometrical stairs.
  • Spiral stairs.                                     

सीढ़ी का वितरण और सीढ़ी सीढ़ी पर इसके प्रभाव को आमतौर पर गुरुत्वाकर्षण भार का विरोध करने के लिए डिज़ाइन किया गया है, जिसमें मृत भार और लाइव लोड शामिल हैं:

1) डेड लोड: माने जाने वाले डेड लोड के घटक हैं:

ए) सीढ़ी स्लैब का स्व-वजन (चलने / चलने-उठने वाले स्लैब / कमर स्लैब)

बी) के स्वयं के वजन ...

लाइव लोड: -
IS 875 भाग II लोड को जनता के लिए तीव्रता 5KN / m2 के UDL के रूप में माना जाता है
आवासीय भवन के लिए भवन और 3kN / m2 जहां निर्दिष्ट मंजिल 2kN / m2 से अधिक नहीं है और सीढ़ियों को भीड़भाड़ के लिए उत्तरदायी नहीं होना चाहिए।

DEAD LOADS: -
सीढ़ी स्लैब का आत्म-वजन जिसमें कमर की पटिया, चलना-बढ़ना आदि शामिल हैं। खत्म का आत्म-वजन (0.5 से 1 kN / m?)

सीढ़ियों के प्रकार
सीधी उड़ान की सीढ़ियाँ।
कुत्ते ने सीढ़ियाँ चढ़ दीं।
नई सीढ़ियां खोलें।
क्वार्टर मोड़ सीढ़ियाँ।
द्विभाजित सीढ़ियों।
ज्यामितीय सीढ़ियाँ।
घुमावदार सीढ़ियाँ।

MAKE A GREEN BUILDING.

What is a Green Building? Procrastinate no longer. The time to build your green and sustainable home is now. Like so many of us, you may have been sitting back and dreaming about building a new home so that it perfectly meshes with the environment. It would be a home that is as eco-friendly and green as it is cozy, functional, and smart to live in. This can be done and the time  can be  now. No longer is it necessary to compromise comfort in order to be environmentally conscious. Because our world is rapidly changing, often in ways that are less than desirable, it is up to each and every one of us to make positive changes. And those changes can begin in that one area we all have the most control over: our home. The concept of a green building was developed in the 1970s in response to the energy crisis and  people’s growing concerns about the environment. A Green Building, also known as a sustainable building , is a structure that is designed, built, renovated, o...

MACHINE FOUNDATION.

MACHINE FOUNDATION. The design of machine foundation involves careful study of the vibration characteristics of the foundation system. Relevant data for the design and construction of the foundation of machine should be obtained from the manufacturer of the machine , prior to the start design.  All parts of machine foundation should be designed for maxim stresses due to the worst combination of vertical loads, torque, longitudinal and transverse forces, stresses due to temperature variation and the foundation dead load. In case, the foundation layout is partly built up of beam and column construction , straight bars should be provided both at top and bottom of the beams and the spacing of the stirrups should be close. The main foundation block should have the designed thickness and should be reinforced both at top and bottom even if the reinforcements are not required from design considerations. Machine foundations  are special types of  foundations  required fo...

Medlum Density Fibre Board (MDF)

Medium Density Fibre Board (MDF)  MDF IS made from wood and other lignocellulose material refined into fibres and reconstituted with a resin binder. Row wood material is normally a single species wood. MDF has homogeneous structure with uniform density, texture and properties throughout, no identifiable grain can be seen at edge, end or face. There are no internal voids or pits and there is no variation in the surface hardness. Unlike plywood MDF doesn't delaminate. It has much higher strength than particle board. Since edges are totally smooth and uniform, costly tipping or beading with strips of wood required for plywood and particle board is not essential. It can be carved, grooved or embossed just like any timber. The surface of MDF is totally smooth and accepts all kinds of finishes - paints, varnishes and laminates. One such type of famous board in the market is 'Duratuff" . It comes in both interior and exterior grade. Duratuff prelaminated boards are also avail...
