But quitting can be a first sign of a serious weakness in the building so that the potential benefit or affect...

The Building cracks are the most common problem in any structure. We all want a home that is both technically sound and appealing, but this isn't always achievable. Natural disasters, soil collapse, construction defects, poor design, and inadequate joints are all factors that lead to the formation of structural cracks. Although concrete fractures can't be totally prevented, they can be handled with the right materials, construction techniques, and design requirements. It's vital to spot such cracks as soon as possible and take precautions. Active cracks are a major problem that needs to be addressed right away since they are structurally unsafe. As a result, it is critical to comprehend the many sorts of fractures, their patterns, and their causes Based.

Building cracks are most common problem found in any type of building. We all love to have a house which structurally safe and beautiful but it is not so easy, one has to overcome natural calamity, soil failure, construction faults, improper design, and inadquate joints causings to develop cracks on the building.Though the cracks in concrete cannot be prevented entirely but they can be controlled by using adequate material and technique of construction and specific design criteria.On timely identification of such cracks and adopting preventive measure are essential. Active cracks causes seriously problem and they need special attention as they are structurally hazardous. So, it is important to understand the types of cracks,crack patterns and their causes and the preventive measures to be taken to control the cracks.

Cracks in a building are of common occurrence. A building component develops cracks whenever stress in the component exceeds its strength. Cracks are classified in to structural and non structural categories. The structural ones are due to faulty design, faulty construction or overloading which may endanger safety of buildings. The non structural cracks are due to internally induced stresses. Depending on width of crack, these are classified in to thin (< 1mm), medium (1mm to 2mm) and wide (> 2mm wide). Internally induced stresses in building components lead to dimensional changes and whenever there is a restraint to movement as is generally the case cracking occurs. There are numerous causes of cracking in concrete, but most instances are related more to concrete specification and construction practices than by stresses due to induced forces.

Cracks are inherent and detrimental elements of building detailed investigation should be carried out regularly to ensure the assessabillity and serviceability of the building. For rehabilitation of cracks it is important to understand the causes and the types of cracks appeared in the structure. This paper shortly describes the causes and types of cracks and their remedial measures. Non destructive testing methods are used to access the strength of the structure at a first instance to know the actual state of the structure whether it will be serviceable/workable or to be demolished. Few case studies were conducted at different public buildings at Gwalior M.P. Political science, economic and archaeological blocks of Jiwaji University. Moti Mahal building.NITM (Nagaji institute of Technology and Management building. Which were reported cracks and they were in suspension to whether it will work or should be demolished. The purpose of this study is to determine the position of structur...

This study was carried out by employing several observatory and analytical techniques to observe and understand the types and nature of cracks associated with building, the causes of such cracks, what could have been done to prevent these cracks as well as reparative measures that could be employed to remedy the cracks. Reconnaissance study was carried out on the structure to discover the nature and extent of cracks with the aid of traditional laboratory tools that can measures and monitor the cracks. From the overall properties and behaviours of the cracks, their possible causes and reparative measures could be established. The compressive structural strength of the key members of the building (slabs, columns and beams) was determined using the non-destructive Schmidt Hammer test. The minimum required compressive strength of 28day old concrete is 25 N/mm2, this is supposed to have attained a strength of 31 N/mm2 after 1year of the concrete life, and the strength is supposed to marginally increase with time. The shear strength of the foundation soil was determined through the shear box test which yielded the soil cohesion to be, c = 0.0355 kN/m² and angle of internal friction, = 25.34° = 25°. The ultimate bearing capacity of the foundation soil which is 409.86Kpa is satisfactory and was calculated using the Terzaghi's formula, Qu = cNc+γzNq+0.5BNγ. The majority of the cracks observed in the building are non-structural cracks. The main structural cracks observed in the building were caused by differential settlement of soil, faulty design and poor workmanship. Some of these are still actively cracking and hence pose a real threat of future collapse. Hence, they require urgent professional repairs. The appropriate remedy to cracks should be such that its nature and causes should be properly investigated and established before repair. Otherwise, wrongly treated cracks would reappear after some time

Cracks are the most common problem encountered in any type of building. Hence, understanding the underlying cause, implementing preventive measures during construction, and employing appropriate treatment methods are of utmost importance. A variety of structural and non-structural elements of the building begin to show fractures due to mistakes made during construction and other inevitable causes. Therefore, it is crucial to spot these cracks quickly and take preventive measures. Although cracks in concrete cannot be avoided, they can be managed by utilizing the right materials, employing proper building methods, complying with the applicable codes and standards, and following intact design criteria. Structural fractures pose a safety risk to a particular structure due to their underlying causes, which may be attributed to deficient design, subpar construction, or excessive loading. Non-structural cracks, on the other hand, are those that result from underlying causes related to moisture or thermal fluctuations, creep, elastic deformation, chemical reaction, or issues with the foundation soil, such as moving, settling, or uncontrolled vegetation. The primary cause of non-structural cracks is internally produced stress in building materials, which typically does not directly cause structural weakness. This research illustrates various types of cracks along with their causes, prevention measures, and treatment methods.

Cracks in the buildings develop whenever stress exceeds their strength. Stress in the building components could be caused by externally applied forces such as dead, live, wind, seismic loads, or foundation settlement or it could be induced internally due to temperature variations, moisture changes, and chemical actions. This paper examined the determinants of wall cracks in buildings, investigating the consequences and remedial measures for resilience and sustainable development. The study revealed that to address wall cracks and enhance building resilience, it is essential to implement remedial measures such as structural repairs, foundation stabilization, proper waterproofing techniques, and effective crack sealing. It focused on the concepts of wall cracks, the determinants of wall cracks in buildings, the consequences of wall cracks in buildings, the remedies for wall cracks in buildings, the effect of wall cracks on the sustainability of buildings, and the prevention of wall cracks in buildings. The study concluded that cracking in buildings can be the result of one or a combination of factors such as poorly designed or constructed foundations, expansive soils, inadequate soil preparation, and others. Therefore, assessing the determinants of wall cracks, investigating their consequences, and implementing remedial measures are vital for enhancing the resilience and sustainability of buildings. Continued research, awareness, and proactive maintenance practices in this area are essential for creating safer, more durable, and more efficient built environments. One of the recommendations made was that during the building construction, there should be structural integrity of buildings which leads to safety from hazards. This will help avert the structural deficiencies that brings about cracks and other issues with extensive repairs, retrofitting, or even demolition and reconstruction.
