The purpose of the present study was to investigate the effect of generative learning teaching based to PATTERN cognitive LOAD on the memorization math of 7th grade students of in the academic year of 2021- 2022. The research method is quasi-experimental with pre-test and post-test with four groups: two control group and two experimental groups. The statistical population of the study consisted of all 7th grade male and female students of District 2 of Mashhad city that 112 person sample was selected by single stage cluster sampling method. The subjects in the experimental group involved in generative learning based to cognitive LOAD in 16 sessions and the control group did not receive any interventions. The research instrument consisted of a 20-questions researcher-made test. To analyze the obtained data, Multivariate analysis of covariance and SPSS version 24 software were used. The results showed that generative learning teaching based to approach cognitive LOAD have a positive and significant effect on 7th grade students' memorization math. Based on the findings, it can be concluded that one of the effective training on math memorization students is the use of generative learning on the based LOAD cognitive PATTERN.

linear static analysis is one of the most widely used methods proposed by the codes for the seismic analysis of structures. Several methods have been presented for determining the static LATERAL LOAD PATTERN. In spite of the simplicity of these procedures, their accuracy, especially for structures in which the influences of higher modes are significant, is not desirable. In this study, a new method is developed to improve the LATERAL LOAD PATTERN in linear static analysis. To achieve the proposed LATERAL LOAD distribution, firstly, the average responses of some structures subjected to some earthquakes are acquired. Then, regarding the dynamic responses of the structures, the static LATERAL LOAD PATTERN compatible with the average responses is developed. Eventually, to derive a straightforward and hands-on LATERAL LOAD distribution, using a statistical study, some relations coupled with a graph are developed. Since the proposed method is developed based on the structural responses resulting from linear dynamic analysis (time-history analysis), it is shown that the suggested way, despite its simplicity and efficiency, presents appropriate accuracy in predicting the responses of the structures subjected to seismic excitations. The developed LATERAL LOAD is applied for three frames with 5, 10 and 14 stories. The inter-story drifts of these frames are achieved under 14 earthquake excitations. After that, the proposed LATERAL LOADs of code 2800 and FEMA 356 are used on these frames and the responses are derived. The outcomes show that whereas the average error of the proposed LATERAL LOAD for these frames is around 7, 5 and 7%, the average errors of code 2800 and FEMA 356 are almost 20, 10 and 25%. Comparing the inter-story drifts for the developed LATERAL LOAD PATTERN with the dynamic results, validates its performance. The developed method is evaluated for a set of structures with different fundamental periods. Results show that the method gives higher accuracy in comparison with the static method of Iranian standard 2800 and FEMA 356. Also, the developed procedure can be considered as an appropriate technique for determining LATERAL LOAD distribution in seismic codes.

Well-known seismic design codes have offered an alternative equivalent static procedure for practical purposes instead of verifying design trials with complicated step-y-step dynamic analyses. Such a PATTERN of base-shear distribution over the building height will enforce its special stiffness and strength distribution which is not necessarily best suited for seismic design. The present study, utilizes a hybrid optimization procedure to seek for the best stiffness distribution in moment resistant building frames. Both continuous LOADing PATTERN and discrete sizing variables are treated as optimization design variables. The continuous part is sampled by Harmony Search algorithm while a variant of Ant Colony Optimization is utilized for the discrete part. Further search intensification is provided by Branch and Bound technique. In order to verify the design candidates, static, modal and time-history analyses are applied regarding the code-specific design spectra. Treating a number of building moment-frame examples, such a hyper optimization resulted in new LATERAL LOADing PATTERNs different from that used in common code practice. It was verified that designing the moment frames due to the proposed LOADing PATTERN can result in more uniform storey drifts. In addition, locations of the first failure of columns were transmitted to the upper/less-critical stories of the frame. This achievement is important to avoid progressive collapse under earthquake excitation.

In this article, it is tried to overcome one of the weaknesses of the current assumptions used in the ordinary pushover analysis. This includes the assumption in which it is assumed that “the first mode controls the response of the structure and this mode remains unchanged after it undergoes to inelastic range”, this assumption is inadequate especially in tall buildings with long natural period of vibration. It seems that the invariant LATERAL LOADs used in this procedure cannot depict these effects. Here, by presenting the modal pushover analysis (MPA) and considering three LATERAL LOAD PATTERNs related to the three first modes of the structural deformation, it is shown that how the higher modes affects the accuracy of seismic response of MRF compared to ordinary method introduced in FEMA273 and non-linear Response History Analysis.

In this paper, the effect of rectangular, triangular and trapezoidal LATERAL LOADings PATTERN on the optimum location of outrigger and belt truss based on energy concept have been investigated. The effect of outrigger-belt truss on shear core system response is modeled by a rotational spring at the outrigger-belt truss location. Optimum location of this spring is obtained when energy absorbed by the spring is maximized. Optimum location of outrigger and belt truss under the effect of three types of LATERAL LOADings PATTERN for structure with one, two, three and four outriggers and belt trusses is calculated. Results obtained from the proposed method for 60 story tall building are compared to those obtained using a standard finite element computer package. The approximate analyses are found to yield reasonable results and give a fairly good indication of actual structure’ s response.

The subject of pile foundation subjected to LATERAL cyclic LOAD is an age-old problem confronted by Geotechnical Engineers. The environment prevalent in ocean necessitates the piles supporting offshore and onshore structures to be designed against LATERAL cyclic LOADing resulting from the effects of sea waves. Such LOADing induces remarkable deterioration in the interactive performance of the soil-pile system. This can be manifested as significant loss in pile capacity associated with increased pile head deflection. The work reported herein is aimed towards conducting extensive experimental investigation on model pipe pile in marine clay under LATERAL cyclic LOADing, subsequently followed by theoretical analysis using finite difference technique. The experimental results are compared with the theoretical results and reasonably good agreement is noted. This paper presents brief description of the experimentation and theoretical analysis carried out with some typical results and the relevant conclusions drawn therefrom.
