An improved Mahalanobis distance-based colour segmentation method for rural building recognition

Aiming at the rapid identification of rural buildings in complex environments from high-spatialresolution images, an improved Mahalanobis distance colour segmentation method(IMDCSM) is proposed and realised in Red, Green and Blue(RGB) space. Vector sets of a lower discrete degree are obtained by filtering the colour vector sets of the building samples, and a standard ellipsoid equation can be constructed based on these vector sets. The threshold of interested colour range can be flexibly and intuitively selected by changing the shape and size of this ellipsoid. Then, according to the relationship between the location of the image pixel colour vector and the ellipsoid, all building information can be extracted quickly. To verify the effectiveness of the proposed method, unmanned aerial vehicle(UAV) images of two areas in the suburbs of Chengdu city and Deyang city were utilised as experimental data for image segmentation, and the existing colour segmentation method based on the Mahalanobis distance was selected as an indicator to assess the effectiveness of this method. The experimental results demonstrate that the completeness and correctness of this method reached 95% and 83.0%, respectively, values that are higher than those of the Mahalanobis distance colour segmentation method(MDCSM). In general, this method is suitable for the rapid extraction of rural building information, and provides a new threshold selection method for classification.

Earthquake-resistant performance investigation for rural buildings in Zhongxiang area, China

We carried out a census of the rural residential buildings of Zhongxiang area＇ s 17 towns. Next, we conducted a sample survey in four townships： Huji, Shipai, Zhangji, and Jiuli. According to the census and sample survey data of the rural residence buildings, we evaluated the quality and earthquake-resistant performance of the rural buildings for the various local rural residential structural types. The results showed that there are four main factors affecting the seismic performance of the local rural residences ： （ 1 ） Foundations are not made appropriately （ such as by compaction or some other fill） but are built directly in the farming soil. （2） Seismic measures are not completely implemented. Structure construction measures are not in place at the junction of the vertical and horizontal wall. The vertical wall joints are not the result of the same masonry techniques as the horizontal joints. There are no lintels above the door and window openings, or if there are any, the length of the lintels is less than 240 mm. （3） The brick masonry wall has low strength. The greatest housing wall mortar strength is between M0. 4 - 1.5, much lower than the strength of the brick. （4） The building material and construction quality are poor. The quality of the mortar masonry wall is poor. The cracks between the bricks are uneven, even in the seams.

After the evaluation and scoring,we give the following recommendations:( i) Strengthening the energy-saving design and improving the living comfort;( ii) Enhancing the application of appropriate technologies;( iii) Improving the level of development environment.

Failure criteria of unreinforced masonry walls of rural buildings under the impact of flash floods in mountainous regions

Damage to rural buildings in mountainous regions caused by flash floods accounts for a significant proportion of economic losses from disasters.The unreinforced masonry(URM)wall is the most vulnerable structural element of rural buildings exposed to flash floods.The failure of a URM wall indicates damage to rural buildings in flash floods.Based on the yield line theory of out-of-plane damage of URM walls and the virtual work method,brittle failure criteria for URM walls under the impact of flash floods were established.According to the field investigation data of the 26 June 2020 flash flood event in Damawu Gully and the corresponding simulation results of FLO-2D,the disaster-causing process was analysed,and the failure criteria were validated.Three building parameters were identified to influence the flood-resistance of URM walls,including the mortar grade,the span-to-height ratio of the wall,and the number of floors of the rural building.The results showed that the cause of the 26June disaster was the diversion of a 50-year flash flood into the residential community on the alluvial fan.The affected buildings were constructed with hollow blocks and lacked flood-resistance reinforcement.The critical failure depth of a URM wall restrained at the top by ring beams(RBs)under hydrostatic load conditions is 1.17 to 1.20 times greater than that of a URM wall without RBs,and the difference is even more pronounced when lowerstrength mortar is used.The flood-resistance of a URM wall constructed with Mb 7.5 mortar and restrained by RBs is almost as strong as that of a URM wall constructed with Mb 20 mortar and without RBs.The span-to-height ratio of a URM wall should not be greater than 1.875 in this case.However,the flood-resistance of a URM wall with RB restraint is almost independent of the span-to-height ratio.The brittle fracture energy of masonry mortar is more crucial to the flood-resistance of 4-edge restrained URM walls if L/Z>1.875.The flood-resistance of the URM wall of the first storey increases linearly with the number of floors.Single-storey rural buildings should be given priority to the use of high-grade masonry mortar and high-density blocks to improve flood-resistance.The failure criteria and the influence laws of building parameters on the flood-resistance of URM walls can provide references for flash flood mitigation and flood-resistance reinforcement of rural buildings in mountainous regions of Southwest China.

A discourse on creating and rendering educational and cultural enrichment services to rural migrant workers by public libraries

As far as China's enormous success in her economic reforms and development is concerned,Chinese rural migrant workers indeed have had their biggest share of contributions.Yet ironically in return,they have only received a disproportionate meager share of benefit rewards.These people represent a huge economically deprived group at the bottom of the social totem pole in China's metropolises.On the whole as a social group,their educational attainment is relatively low as compared to their average urban coworkers.As such being the case,their rights to access some of the cost-free cultural and educational enrichment programs in the society are limited and not always assured.Nevertheless and in general speaking,they manifest a strong and consistent desire to acquire all sorts of new and practical knowledge by means of accessing the resources and facilities of their local public libraries.It is suggested in this paper that public libraries are in a good position to give strong support to the central government's strategic planning for the development of a public culture service systema).In implementing such a government initiative with an unswerving purpose of advancing social justice and equality,public libraries should strife to provide as many as possible their library services at no cost to the public,especially to those socially deprived rural migrant workers.

Investigating the Problems and Proposing Solutions for Rural Residential Buildings in Northwest China

With the increasing income of the rural population in Northwest China,people’s sense of happiness and gain is also increasing.However,the improvement of housing conditions is lagging behind the increasing income levels.In recent years,the government and owners have paid much attention to this issue.The local government has successively issued relevant guidelines and policies to encourage owners to reconstruct their houses and improve their housing conditions.Before improving housing conditions,the existing housing problems must be identified.In order to have a comprehensive and in-depth understanding of the problems of rural residential buildings in Northwest China and to propose corresponding solutions,90 representative rural residential buildings of three provinces in Northwest China have been selected for investigation,and mass data have been obtained.Upon analyzing these data,it has been found that there are problems in five aspects of rural residential buildings in Northwest China:architectural style and functional space layout,energy utilization and dissipation,design,construction,as well as structural safety and seismic measures.Valid solutions are proposed to address these problems,which can also provide a reference for the government and enterprises engaged in the architecture,engineering,and construction(AEC)industry in rural areas.

高延性混凝土加固单层砖木结构农房振动台试验研究

为提高我国农村砌体房屋的抗震性能水平,采用高延性混凝土(HDC)条带加固的方法,设计了两个缩尺比为1∶2的砖木结构模型,对加固模型与未加固模型进行振动台同台对比试验。对比分析了地震作用下两个模型结构的加速度响应、位移响应、扭转效应和破坏形态,并对其抗震性能进行评估。试验结果表明:单层砖木结构农房的整体抗震性能较差,结构的自振频率低、位移反应较大,扭转效应明显,在8度设防地震作用下接近倒塌;经HDC条带加固的模型结构自振频率增大,位移反应相比未加固模型更小,山墙外闪现象得到明显控制,结构扭转效应的破坏作用明显减轻,在9度罕遇地震作用下HDC面层只出现轻微受损,可达到“大震可修”的性能目标。采用HDC条带加固法可有效延缓结构在强震作用下的刚度退化,增加结构的耐损伤能力,并有效提高此类砌体结构的整体抗震能力。
