Castellated steel beams are those members which are made from hot rolled steel I-section firstly by cutting the web in zigzag pattern and rejoining the two halves by welding together to form a hexagonal castellated beam such that the depth of section will be increased. Generally, the openings made in the web are with hexagonal shape; however, octagonal shape of web openings is typically obtained by providing spacer plate which is utilized to increase the depth of beam. Nowadays, using castellated beams in building construction becomes very popular because of their useful functions such as ease of service provision, strength and low cost. This study focuses on improving the behavior of hexagonal and octagonal castellated beam with spacer plate. The ultimate strength of the original (parent) Isection beam increases due to the increasing its depth. The increment of castellated beam depth; however, leads to post buckling in its web and to many other modes of failure when these beams are subjected for loading. Hexagonal and octagonal castellated beams which are fabricated using parent I-section (IPN140) are analyzed using finite element model (FEM).The analysis results revealed that using ring stiffeners around edge of holes contributes effectively in strengthening the web. It was found that using ring steel stiffeners can reduce the stress concentration around the edge of holes and improve the behavior of these beams by increasing the ultimate strength and minimizing the deflection. From the numerical (FEM) results obtained by using ANSYS14, it is concluded that ultimate strength of castellated beam can be improved by providing spacer plate and ring stiffeners around the web hole. Also, the results showed that ultimate strength of octagonal castellated steel beam can be increased up to (53%) more than the parent beam (IPN140) with providing only (13.0%) weight of steel (spacer plate plus ring steel stiffeners).

This study assesses the possible use of local raw materials (clays) for producing expanded clay pellets and test the product with American standard for test materials (ASTM) and according to ASTM C 330.For using them as lightweight aggregate in different construction applications, like thermal insulation, lightweight structural concrete , decoration pieces ,etc. The clay was collected from AlAnbar province. The clay was bloated at 1150 C° without adding any impurities ,just mechanical treatment and perfect firing program, in order to obtain good bloating coefficient that is related with firing parameters (access time, temperature, socking time). We got the results of the match determined by the American specification (ASTM C330) and in which is considered lightweight aggregate. We got density about (280 kg / m 3 ) which is much less than that determined by ASTM where the aggregate lightly if the density is less than (880 kg / m 3 ).
本研究评估了当地原料(粘土)用于生产膨胀粘土颗粒的可能性，并根据美国试验材料标准(ASTM)和ASTM C 330对产品进行了测试。将其作为轻骨料用于不同的建筑应用，如保温材料、轻质结构混凝土、装饰件等。这些粘土来自阿兰巴尔省。在不添加任何杂质的情况下，在1150℃下对粘土进行膨胀处理，只需进行机械处理和完善的烧制程序，即可获得与烧制参数(准入时间、温度、保温时间)相关的良好膨胀系数。我们得到了由美国规范(ASTM C330)确定的匹配结果，其中被认为是轻质骨料。我们得到的密度约为(280 kg / m 3)，这比ASTM确定的密度要小得多，如果密度小于(880 kg / m 3)，骨料就会变轻。

In this paper, a mixed transform method is proposed based on a combination of wavelet transform (WT) and multiwavelet transform (MWT) in order to denoise medical images. The proposed method consists of WT and MWT in cascade form to enhance the denoising performance of image processing. Practically, the first step is to add a noise to Magnetic Resonance Image (MRI) or Computed Tomography (CT) images for the sake of testing. The noisy image is processed by WT to achieve four sub-bands and each sub-band is treated individually using MWT before the soft/hard denoising stage. Simulation results show that a high peak signal to noise ratio (PSNR) is improved significantly and the characteristic features are well preserved by employing mixed transform of WT and MWT due to their capability of separating noise signals from image signals. Moreover, the corresponding mean square error (MSE) is decreased accordingly compared to other available methods.
